... disappeared. Do to some strange work schedules I have not take Wellbutrin for over 4 days (usually take right before bed) but I do not feel any negative effects just less anxiety. I realize you are suppose to taper off, but by accident I forgot to take, and feel ok going into day 5. How will I know that I am ok or how long will it take for me to know that I am ok to just suddenly stop taking wellbutrin? Or should I be ok if I came this far? Can anybody please give me some advice???
