I had very similar initial symptoms on Wellbutrin. They calmed down after a few days. I think they were at their worst at about 3 days. So you may be experiencing something similar. Definitely call your pdoc for advice. I settled down on the med and then later when we increased the dose, I went through similar symptoms, though shorter lived. I have been on Wellbutrin now for a couple of years and am doing well on it.

There are at least half a dozen companies that make generic Wellbutrin and I believe only 1 of them has had problems and made a generic that does not work well. So don't rule out generics just because of this one company, because generics can save you a lot of money. My prescriber has written into my Buproprion prescription that generics are allowed except from this one company.
