I'll try that next time.
The skill is to always keep the tablets with you!
I did try triptans on a few occasions but I didn't really notice much difference to migraleve; I guess I don't get them often enough to test whether they work or not. That and the cost (£7 for two) put me off!
That said.. I can honestly say, when a migraine is in full flow I would pay ten times the cost to get rid of it..
