My migraine med is Cafergot [1mg ergotamine and 100mg caffeine]. Must be taken very early in the headache. Start with two, then one evey half-hour until pain stops, to a maximum of six, and ten a week. Not to be mixed with certain other drugs. Makes me nauseus, therefore I use 1/2-1 gravol also. There are much better stuff available, but expensive, so government only provides this. If you already consume a lot of caffeine, it may not be advisable or as effective. Ask your doctor, or if no help there, see a neurologist. Most common sure sign of migraine are visuals, not to be confused with what you see after shining your flashlight in the mirror and staring at it.
