Pretzel1234 if that question is for me, since you posted after my post and I am on Welbutrin at the moment, I do have a lot of nausea throughout the day but I can not say it is from the Welbutrin. I believe it is from my GAD as I've had nausea many times from anxiety even before I was on Welbutrin. Although this is true, a side effect of Welbutrin can be anxiety because it has a stimulant effect and this can be exasperated in combination with caffeine.
