Now, sometimes combining wellbutrin with an ssri such as Paxil will be done because that can help with the weight gain
and sexual dysfunction problems, but quitting
Paxil to go on wellbutrin is not likely to help with anxiety -- depression, maybe, but not anxiety because, again, wellbutrin is very stimulating. If this were me, I'd not take the Wellbutrin, stop the whole process, and get a psychiatrist before I proceeded further if your doc isn't one.
