Precisely. That's why it is a sign of respect towards other members to express one's thoughts in a way that other people can understand. This is particularly the case on the internet where you don't really know who it is you are talking to.
If Philippa doesn't even take the time to express herself in an intelligible way, why should I take the time to read it?
Maybe I am indeed harsh here, but the way Philippa talks to people on here is a clear sign of disrespect in my eyes. And she hasn't always posted like that.

I don't know. For some reason, though, you do.

I also have difficulties understanding Phillipa's writing. I would never have perceived her writing as disrespectful.
At the risk of being disrespectful, I am concerned about you. You seem to be very angry and frustrated. Why is that?

Well, I do. Just like it would be disrespectful if I chose to talk to my university professor the way I talk to my friends from high school.
On other forums, which are by the way much healthier than this one, Philippa's writing style would not be tolerated, for the very reason I described.
> You seem to be very angry and frustrated. Why is that?
Oh, this is not so much the point. Both my comments on your treatment procedure and on Philippa's writing style have been simmering for a long time now, and I refrained from saying anything about it for quite a while. That may make it look like I was angry or frustrated.

Scott, I am interested as to whether prazosin deepens sleep, reduces early waking and so on.
Do you have an opinion on that?

Those are great questions for which I don't know the answers. I'll see what I can find out. It most certainly suppresses nightmares and is supposed to smooth sleep out in general according to the PTSD studies.

The best med ever for my PTSD symptoms was topamax.
Oddly, NRIs seem to help me a bit.
zoloft and celexa were good on irritability but the apathy was just too much.

The apathy is one of the things I dread most with the SSRIs. Hopefully, I won't have to return to them.Thanks for the information regarding Topamax.

This stuff is still working - robustly. It is as if a light switch was turned on. I haven't felt this well for as long as I can remember - decades. I am not even 1/2 well yet, but I feel that I am on my way to remission. See how optimistic I get? It is a sickness :-).
Please pray for me. I could use all the help I can get.
Currently:Parnate 80 mg
nortriptyline 150 mg
Lamictal 200 mg
Abilify 10 mg
lithium 300 mg
prazosin 6 mg

Today is day 6 of my positive response to treatment. Still going strong.
Relief. Finally.
My mind is reawakening after 30 years of existing in a vegetative state.
Keep those prayers coming!

This is an interesting abstract that reports a downregulation of NE alpha-1 (prazosin) binding with antidepressant use.

AbstractThe aim of the present study was to examine the effect of chronic antidepressants treatment on the density of a1-adrenoceptor (AR) subtypes in rat brain. Density of total a1 and a(1A)- and a(1?)-ARs was measured in cortex and cerebellum of rats treated with amitriptyline (AMI), desipramine (DMI) and fluoxetine (FLX), (10 mg/kg body wt), for 30 days, using [³H]prazosin in presence and absence of WB-4101. The density of cortical total a1-ARs was significantly decreased with AMI (54%) and DMI (25%) treatment, without altering the affinity of the receptor. Fluoxetine did not alter the density of cortical a1-ARs. The density of cortical a(1A)-ARs was also significantly decreased with AMI (85%) and DMI (50%) treatment, without affecting the affinity. The density of cerebellar total a1-ARs was significantly decreased with AMI (37%), DMI (50%) and FLX (70%) treatment, without affecting the affinity for [³H]prazosin. The density of a(1A)-ARs was significantly decreased with AMI (67%), DMI (59%) and FLX (92%) treatment. a(1B)-AR density was decreased only with FLX (47%) and DMI (47%) treatment. Correspondingly the basal IP3 and NE (10 µM) stimulated IP3 levels were significantly decreased in AMI (47%), DMI (22%) and FLX (48%) treated rat cortex. The results suggest that chronic antidepressant (AD) treatment down-regulates the cortical and cerebellar total a1-ARs in rat brain. However, a(1A) subtype is predominantly down-regulated by AMI and DMI, where as FLX affects cerebellar a(1A)-ARs. The region-specific and subtype specific down-regulation of a1-ARs density, which occurs after prolonged AD treatment, may underline the therapeutic mechanism of action.

Hi Bob.
It was nice of you to notice my post. It might be an important observation that prazosin has produced such a significant improvement in my condition.
Just to let you know, I performed an experiment to verify that prazosin was the agent responsible for my improvement. I discontinued it for 36 hours and observed that I relapsed pretty hard. I was able to recapture the antidepressant response immediately upon the reintroducton of prazosin. Upon titration, I settled on 6 mg as the dosage. Hopefully, this is the dosage that will bring about a full remission. My instincts tell me that it will.
> OK, so in lay terms what does this mean?
Chronic (long-term) antidepressant treatment with certain drugs causes the norepinephrine NE alpha-1 receptors to downregulate by reducing their numbers. Prazosin blocks these same receptors, thereby producing the same net effect.
I am, of course, extremely interested in the way prazosin might work for others as it now works for me. (Please God, let it continue). Perhaps prazosin has been overlooked in the treatment of TRD.
For now, I would say that prazosin might work best as an adjunct to antidepressants for people who have a history of childhood physical abuse, emotional abuse (including bullying), or neglect. It may be that some people have a backdrop of PTSD acting to drive depression. Does pazosin also work for other subtypes of depression? I don't know.

I'm lost here.

Prazosin is Minipress, right? I was wondering if it blocks overactive NE, or were you saying the reverse?
How has it affected your sleep? I wonder if my sleep is disrupted by too much NE. Certainly something is doing it. I'm not in a hurry to try clonidine.

> Scott, can you explain simply how prazosin is different to clonidine.
Prazosin (Minipress) was originally developed as a treatment for hypertension. It was discovered by accident at a VA hospital that it was useful to treat PTSD.
Clonidine works the reverse of mirtazapine. It actually stimulates the NE alpha-2 receptors located on the presynaptic membrane. This, in effect, turns off the presynaptic NE neuron. Prazosin, on the other hand, blocks the postsynaptic NE alpha-1 receptor, thereby reducing NE activity.
Prazosin seems to be particularly successful at treating the disturbed sleep and nightmares associated with PTSD. I guess you are already aware that clonidine can produce or make worse depression. I find prazosin to be extremely clean. I noticed that I don't remember my dreams as much as I had before starting prazosin.
Good luck with whatever you decide to do.
