"i was started on 75mg at first and for 2 weeks i had the worst side effects.  i literally thought i was going insane. the doctor told me it was normal and ride it out another week.  so i did and it passed.  they moved me to 150mg xl and it worked wonderful for years.  a few years in i had to go up to 300 xl but i was still panic free and depression free.  until recently when it stopped working and i had prozac added to the mix.  i would recommend welbutrin xl to people.  just know you can push through those awful side effects for a few weeks to feel better."
