Hi,
I was on paxil for about 2 years, and also experienced many side effects, although none as severe as yours. I experienced severe tremors, and it caused a lot of problems with sleeping. Mainly, i couldn't stop sleeping! It also made me very nauseous. I think that it really depends on the individual, but i've found celexa to be much better for me. I've been on it for about 2 years now as well, and have had no side effects. Good luck! Remember, that those kinds of medications take around 3 weeks to start working, so it might be a matter of time. I would see your doctor to be sure though.
