Thanks undopaminergic for your reply but that was exactly what I was getting at. I don't understand a single sentence on that link, I've looked at it before.Put it this way, is it like citalopram v's escitalopram. I know citalopram is weaker in concentration because it's slightly different. Which is the weaker between modafinil and armodafinil?
You're obviously well read/educated in chemistry and I'm not, could you explain it in a different way? The shiny objects caught my attention again and it was all too much to take in, or are you telling me that modafinil is the patent extender, which I do understand because that would explain the price.
Thanks C
