Paxil seems to be stronger than other ssris, possibly because of its larger effect on choline receptors, which accounts for some its difficulties.
Prozac, of the ssris, has the least
weight gain and is easiest to quit. Paxil seems to work better for anxiety, but there are other ones you can try as well if you don't want to do Paxil. And nobody can tell you which will work for you -- it's just too individual.
