Re: Wellbutrin worked first time, but won't work again...!
I had the same experience! It's SO discouraging ...
Anyway, I did a little research, and two forms of the generic Wellbutrin XL (slow release) have been recalled - because they do not work like the original. One is made by Impax, one by Teva.
I'm on a quest to get my insurance company to cover the brand name drug - they still list the faulty generics as their alternatives. My second option is to get an Rx for Zyban, which seems to be a little less outrageously expensive than Wellbutrin XL.
Do Not Give UP!
