I've taken antidepressants for years (20 mg prozac) and have sometimes tapered off them, restarting later. I can barely tell that I'm taking them, I feel 100% like myself on--and off of--them. I know they do something because when talking about difficult traumas with my therapist, if I'm not taking flouoxetine I will get choked up to the point I can't speak. That's the only difference I can perceive. My dose is not a "happy pill", it simply smooths out some extreme lows. Tapering off (a few weeks of 50% exponential declines) I've done because it's recommended, but again, I've never noticed any affect on mood before, during, or after.
after a number of years, a small dose of lithium (300mg) was recommended by a psychiatrist who stood apart (at least in that respect), and it was magic at mood stabilization, I never before even realized that I experienced hypomania (and I took it for anxiety), I just thought I was "bold".
(Lithium is not a drug, it's an element, taken as a metallic salt. It occurs naturally in the water in various parts of the world, and those populations have been studied and suffer lower rates of mental illness. My shrink said his recommendation was based in conjunction with the prozac I was taking, i.e. a known correlation. Bipolar II is a different mental condition than bipolar I, and somewhat slippery/loosely defined)
The extreme anecdotal stories people report online as in this forum strike me, an experienced but likewise only an anecdotal user, as more an artifact of underlying emotional distress rather than a result of the drugs.
I just wanted to contribute a different voice to this topic.
I should add, I do have "extra money" and am able to pay extremely qualified and expensive doctors, an option that is not available to everyone, including those with full public health services.
