I totally agree with you. My friends on generic Wellbutrin had some serious difficulties. I was able to do some research and found out that there was an "authorized generic" (I hope I'm using the right term.) from Watson Pharmaceuticals. I told them to have their respective doctors (or should I have said the pharmacies?) make sure that they got the authorized generic.
I'm surprised that we haven't heard more (and had more lawsuits) about generics that are not exact duplicates of the original. I'm also surprised that the FDA isn't more stringent about this issue.
