Last week I was prescribed 20mg of Paroxetine anti-depressants, not for depression but for anxiety. I've been taking them for a week, but all they do is totally kill my sex drive, make me tired and groggy with blurred vision, and make me yawn constantly and feel sick, but im not feeling any different. The only good thing is the next morning when I feel "normal" which is the best I feel all day. How long can I expect before they actually do something, and will the side effects go away?
