It may take a combination of multiple AD to get you to the right level. And that can be a frustrating process too. It's like playing with a chemistry set. I have been on the same AD for over 10 years and have had to try adding at times.. Prozac worked for a while- felt better than ever but it only lasted a brief time and didn't work again after I was off it and went back on. Tried a few other SSRI but they don't balance me out. I've found that I have to research meds and then suggest to my doctor- its actually my PCP that prescribes. After years of seeing a Psych, and trying different meds, she said we were out of options which was unacceptable. so I did my own homework and found one doctor,thePCP, who suggested new alternatives as well. I'm at a low point now and still searching for the right combination. I wish you all the best.
