My fiance just started taking the pill form of Imitrex and, like you, says it is an absolute saviour.
She gets migrains pretty bad, but not with the consistency and intensity that you guys mention. She is a tough one, so when she gets hit with one of these, I know she is really hurtin'.
Cart, I hope all is well for you in the future and you find some form of relief for your suffering.
Just thought I would share.
