I have been taking Wellbutrin for 8 days now. I was told by my pharmacist that it would take up to 4-6 weeks for my anxiety attacks to cease, so I am desperately waiting to feel better. One thing I have been experiencing since yesterday though is my sense of smell has intensified BIG time... almost to the point of making me ill... I have also lost 2 1/2 pounds in the last week, so it will be interesting to see if that keeps up. I really hope this stuff doesn't cause some of these other side effects I have been reading about.
