I have a prescription for Prozac at the pharmacy waiting for pickup right now! I took it for several years a decade ago. The worst side effect was apathy which came on so slowly I wasn't really aware of it. ( I'm planning to watch for it and augment with Ritalin or Adderall if necessary). The other side effect...sorry to mention it but yes I did gain weight about 20 pounds. The weight gain started after about 6-8 months.

So why am I taking it again? Well for me it worked better on anxiety and agitated depression than anything else and there really weren't any other side effects except nausea (other than the apathy and weight gain.)

Peoples experiences vary so widely even with the same drug so you never can really tell. I hope it works well for you and me both!
