I was on paxil for about 3 years it will take between 2 and 4 weeks to feel the positive affects till then your going to feel like shit .Paxil is an awseme drug ,but it messes with your libido.wellbutrin supposeldy counteracts this side of affect but not that was not the case for me.Im currently on celexa it works the same as paxil but not quite as well the side affects are less also. dom,
