"this is a really interesting medication based on the wide variety of experiences people have taking it. one person here said they constantly forgot things and had thoughts of death *before* taking wellbutrin, whereas those are the symptoms i have *after* as side effects of wellbutrin!  also, i did have immediate success with this exact same medication dosage around 9 years ago (was on it for 3 years until it got less and less effective and i quit). this time, i&#039;ve only gotten those negative side effects i mentioned. my doctor says give it 6 weeks, but it&#039;s been 4 and no benefit at all. strange. apparently, wellbutrin&#039;s effectiveness can change over time even for the same person!"
