I am on Prozac and find that it is helping me a lot. It's open to more neurorecepters than other medications like zoloft, which is what I had before. I didn't feel any bad side effects from either of them, but every person is different. If you've never been on meds before, I think most doctors start you on 10-20 mg of it and fiddle with it until you start to feel better. Right now I'm on 30mg and it seems to be the right dosage for the time being. good luck
I tried it last year and despite the doc doubling the dose, it really didn't do much for me. While on it, I had some side effects but these were nothing major.
Although it didn't work out for me, it might just work for you. Good luck with whatever you decide!
