Imitrex
"It keeps my migraines from blowing out into a severe migraines, but it takes close to an hour to kick in and when it does I feel extremely sick, very fatigued for two hours after.  Then I have just a mild headache, but I feel like I have a hang over and become forgetful and weak.  It is definitely a trade off, but as severe as my migraine can get, I'll take with this until I find another type of medication."
