I've blacked out too many times to count...I'm also an alcoholic.
The worst that's ever happened was waking up in my own bed with a hospital bracelet around my wrist. I had no recollection of even an hour past picking up a drink. I had apparently drank a ton of vodka, swallowed 10 xanax...threw up, fell into a sliding glass door, fell twice on my tile kitchen floor, hit my head, had to be taken to the hospital, had such low blood pressure they could barely get an IV in me, had a seizure...and almost DIED right there at the hospital. I put my family through hell. I don't remember a single bit of it. The scariest part...it didn't stop me from drinking again and having blackouts again.
Blackouts are very very dangerous. They are also a sign of alcoholism. I cannot drink safely.
I'm glad you are here posting. I'm sure you will find many others who have experienced the same things.
