Is there any way you can take Zoloft instead of Paxil? It's really safe when BF (almost no transfer into milk from what I have read online by those taking it) and supposedly the side effects and difficulties with tapering off are better.
That said, I'll chime in since I took Paxil off and on for years. It can be a great drug for some people, but expect to have some anxiety, twitches, weird things for the first 3 weeks. When I first got on it I was on a dose of 20 mg and it took about 6 weeks before I felt the full effect, but it really did help me with both depression and anxiety.
If you do end up taking Paxil, please do not miss a dose, and always have your medication on hand, don't forget to fill the prescription well in advance of it running out. I ran out of Paxil a few times and the immediate withdrawal effects are NOT GOOD. It felt like my brain was being given electric shocks. I could not concentrate and felt nauseous and very out of it. When I took my Paxil again the effects subsided. These same effects plagued me when I went off Paxil (several times, and then months or years later I went back on - I took it 3 or 4 separate times). No one told me about them ahead of time and this was in the days before the internet and Dr. Google, so I just thought I was going crazy. This smilie

: really helps you visualize how I felt.

Anyway, the last time I tapered off Paxil, I did it really carefully. You just can't go too slowly. It's important to know about the withdrawal symptoms BEFORE you go on the drug, so I hope your healthcare provider talked about this with you.
If I am ever in need of an antidepressant again, I will try Zoloft before trying Paxil again. It is just not my favorite drug due to the withdrawal effects. I also had a decrease in sex drive and the weight gain that one poster mentioned - as she described, I did not feel sated after eating. I also felt kind of apathetic on the higher dose I was on. BUT it drastically reduced my anxiety, drastically. Helped me cope at a very difficult time, when I had been having several panic attacks a day. And also helped the depression somewhat. Like every drug there are risks and benefits.
Good luck to you. Depression sucks.
