migraine
"I avoid taking Imitrex if I can because I experience so many side effects from it. I get jaw and shoulder pain/stiffness, pain in the back of my neck and scalp, headaches, drowsiness and I just generally feel weird and awful after taking it. After 2 hours or so, my migraine goes away and the awful-ness of the Imitrex lessens so that is why I do take it occasionally. Every time I take it, I'm reminded of how badly I need to find something else."
