Mine last for hours and hours. Intense. Heart racing, sweating, dizziness, confusion, stumbling/falling, vomiting, head hurting, difficulty communicating.
Last Friday, I had pretty much one solid attack, heart rate nearly doubled throughout from about 6:30 a.m. until after midnight.
I posted a very similar question (only more whiny).
Hang in there - I stopped one after only a couple hours today. I feel super empowered, and you're going to learn to do that as well. :)
Hugs!
