Ick. I take Relpax, which makes me slightly goofy for a few hours after taking it, but the SHEER RELIEF they give is so worth it. Most of my migraines tend to masquerade as regular bad headaches, not the oh-god-i'm-going-to-die ones that I have on occasion, and I can't tell they're a migraine until I take OTC drugs and wait a couple of hours and it doesn't get any better. And then it usually takes two hours for the Relpax to kick in but when it does ... bliss.

I've had a couple last for a week, but those weren't horrid headaches, just bad ones. The longest one of the really really bad ones lasted a bit over two days, and it 3as making me so sick to my stomach I didn't realize until the second day that the headache was causing the nausea, and not the other way around. :) But that was before my happy pills.
