Hi all, I have been reading alot of past posts regarding Wellbutrin. One thing I have not seen is about insomnia as a side effect of Wellbutrin. I take Wellbutrin SR 300 mg. Last night I forgot to take my Flexeril. At 3 am, I was wired. I realized I had forgotten to take it. I took it then and it took quite awhile to hit me but I am thinking that maybe the Wellbutrin made me more wound up than usual. Has anyone else had this side effect with Wellbutrin? It does give me more energy during the day but I don't like to be so wired at night.
