migraine
"I've been using Sumatriptan for my menstrual migraines for 5 years or so now, I'm 24 years old. Although I get several of the listed side effects (muscle weakness, tingling & burning sensation, drowsiness to name a few), it works so quickly at getting rid of the pain I couldn't be without it now. The side effects only last an hour or so, so it's completely worth it."
