I got some mild headaches when I was on Wellbutrin. I haven't gotten headaches from anything else, but I rarely get side effects from meds, and I have gotten a couple of other effects in the past. Headaches are not an uncommon side effect, and if it persists, especially if it's getting past a month, then you should consider a different medication.

What are you taking that's making you so sleepy? I used to take benzos...and I could sleep 16 hours a day every day!
