Prozac, Zoloft, Effexor, amitryptiline, Paxil,
trazadone, Serzone...all but MAOIs.
They either had no effect or the averse effects outweighed the positive (zoloft kept me afloat by making me numb to all feelings altogether).
Finally, in 2003, I was in a study for treatment resistant depression and Lexapro quite literally saved my life. I was later switched to Celexa for financial reasons. I had no problems transitioning and have taken it for the past six years.
