migraine prevention
"I'm currently on 150mg daily of this medication and it does a great job in preventing headaches. A few smaller ones get through that ibuprofen will take care of but the amount of serious headaches and migraines have decreased significantly. The only difficulty is because the pills are so lightweight they do not go down easily. I have to chase it with food (such as taking it during dinner) or else the pills get stuck and cause pretty bad heartburn-type difficulties."
