Migraine
"I take Sumatriptan for menstrual migraines and this medication has been an absolute lifesaver for me. If I take a 50 mg tablet  when the migraine starts, I have 100% relief within 30 minutes. If I wait until the migraine is really bad then it takes about an hour to kick in.  My migraines generally last 2 days and the first dose wears off in about 12 hours so I usually have to take another dose. The only side effects I experience are a slight head rush that goes away after about 10 minutes. I would recommend trying to take a nap after taking this medication which really helps."
