> Rick, you make such good points -- not only in this thread, but much of what you've posted on this subject -- and many of them are things I try very hard to keep in mind when considering medications. I'm going to add one more consideration that I think supports your point:
>
> Similarity of mechanism does not necessarily correlate to similarity of the subjective experience of treatment. We can use our response patterns to medications to speculate about the biochemical underpinnings of our disorders, but it's still speculation. It's often very helpful speculation, but that still doesn't make it evidence. Knowing the serotonin-norepinephrine reuptake inhibition ratio of one medication and expecting that recreating that ratio as closely as possible by combining other medications will produce the same results really is too facile -- all of this is more complex and more subtle than that.
>
> I certainly agree that response patterns can be a very good guide for selecting medications. Response patterns are a great tool -- although I'd like to note that I think it unfortunate that we all seem to know our response patterns, since it indicates a lot of failed med trials. I know from my own history of failed medication trials that I respond better to medications which affect norepineprhine. I don't know that that fact means I am deficient in norepinephrine -- I only know that, on average, I respond better to medications that affect NE than I do to meds which don't.

> I'm obviously interested in this subject, or I wouldn't be here. I am just concerned that sometimes speculation leads to unrealistic expectations, which can lead to disappointment.I seem to respond immediately to norepineprhine meds but unfortunately cannot tolerate them due to urinary difficulties and blood pressure rise.But they make me feel better from day 1. I have adhd in addition to depression so that could be the reason I respond to them.
