Wellbutrin is NOT a treatment for Anxiety, if anything it will cause more anxiety.
Ask your Doc for a referral to a Psychopharmacologist. They know what they're doing.
I need some more information. You took WB then got panic attacks then stopped, and in that order?
How long did you take it, and why did you stop and how long ago? Assuming you didn't like the WB, why didn't you switch to another med?
What pills do you have that knock you out at night?
