I can comment on wellbutrin and xanax. I liked wellbutrin, it made me feel better, I started off at a low dose. And when things in my life changed ie I stopped talking to my mother, I could tell I didn't need it anymore and I weaned off it. But the interesting thing to me was that I could tell. Like my brain was too bouncy because it wasn't weighed down anymore by my mother so it didn't need wellbutrin to keep making it that bouncy.

I went on xanax at a time in my life when I would start crying every time I took a step. If I stayed still I was okay. Except I had to move out of my apartment! I eventually weaned off very slowly by sleeping thru the yuckiness, it wasn't that bad but I wasn't taking very much. But you don't seem the type to overdo it, honestly.

Could your daytime sleepiness be due to sleep apnea? Have you had your tonsils and adenoids taken out?
