JChandler,
You need to discuss with your doctor: your dosage and the differences between wellbutrin SR and XL...my body prefers the SR generic. I had ringing in my ears, but it went away after the first month. I'm on 300mg a day, and my nurse says that's the limit. You also need to read the package insert to the wellbutrin; it's very scientific and has all the info you could possibly need. I believe, you need to double check, this insert says that siezures are a possible side effect.
Have you been on the wellbutrin only for six to eight weeks yet?
