migraine
"Went on Methergine after being in the hospital and several years of changing preventive medicines, with migraines only getting worse and clustering longer. Once on the dose (had to go up 1 pill a day each week) had the best 2 months of my life. Month off - back to horrible. Back on - good month. Then this month have had a 10 day cluster. Doctor says change of weather (to winter), and other issues may be the cause. Not to give up."
