I've been going through my HA for exactly a year now. I havent really drank but when i do, I sure feel it the next day. A couple weeks ago, i decided to celebrate the ending of school, so i drank the most that I have since my HA and depression kicked in (so the most in about a year). The next morning was hell. My legs and arms shook really bad, i was even having trouble eating my food with my fork (stabbed myself in the face with my fork). Every time i stood up form standing, i felt a horrible case of vertigo. The room wouldn't necessarily spin, but i was extremely light headed and felt like i was tipping over, but whenever I was seated, this sensation never occurred. Again all this happened AFTER i drank. It's been about 2 weeks since, and still somewhat not 100%, but definitely a lot better. I must say, it is very unnerving when it happens, and definitely makes you question the doctors when they say there is nothing wrong with you.
