migraine prevention
"This medicine has helped my migraines significantly. I had been having 4-5 migraine attacks per week and now am down to 1 or 2 every few weeks. Some weeks I don't have any. A huge relief. I had migraines for years. Missed work, severe pain and this medicine is a huge relief. I do feel tired and sluggish and may be related to this medicine but I don't know for sure. I will take that side effect over the pain of a migraine any day."
