ADHD
"I have been taking Wellbutrin for 8 plus years. Then went to SR, then XL.  Helped with my ADHD with Adderall too.   Went off for about a year and started back. 
To save money went to generic 150mg XL - they were great.  When Dr. suggested increasing back to 300mg daily (as previously) I agreed. I started taking the 300mg XL generics - the symptoms returned.  I noticed when I opened the bottle there as a noxious odor given off.  After 4 weeks couldn&#039;t stand the smell and returned the rest of the pills to my pharmacy.  They replaced them and said they would look into the problem.  The 150 mg SR generics stink too. Only the 150mg XL generics don&#039;t."
