cluster headaches
"Absolutely love this medication. I suffer from chronic migraines and daily headaches. I take 4mg of Zanaflex at breakfast, 2mg at lunch, and 4mg at bedtime. I'll take 6mg during a migraine attack and it helps tremendously with the pain, helps me sleep, and actually helps with the nausea.

Zanaflex made me very drowsy at first and still does taken at doses of 4mg. Overall, incredibly helpful drug!"
