I took Wellbutrin SR 2 years ago and never had a problem. Started taking it again and have a number of side effects. I have been on it for over a month (150 MG 2 times daily). Since being on it, I have had severe headaches and migraines (had problems with migraines before, but not like the ones now), severe insomnia, memory problems, dry mouth and frequent loss of appetite. I have always been able to take prescription meds or Excedrin Migraine for headaches and they always helped. Now I can't get rid of my headaches since being on Wellbutrin. I have been taking Ambien 10MG for the insomnia, but that only helps for about 5-6 hours. Without the Ambien, I could go 2 days without sleeping.
