Ugh -- SEE my memory issues!!

Actually, the ephedrine might help your carotid sinus hypersensitivity, too.

"Medication management of vasodepressor carotid sinus syndrome is less successful: Ephedrine has been reported to be useful, but long-term use is limited by side effects; dihydroergotamine is effective but poorly tolerated; fludrocortisone produces good results but its long-term usefulness is limited due to adverse effects.6 Midodrine use appears promising based on a recent small, randomized, controlled trial.17"

BUT, I would want a doctor to clear this FIRST!
