Hangover cure?

I’m in purgatory. I think I must have died over the sink basin. I was at my friend’s house party last night, having drank incessant amounts of alcohol (some of which I remember) and now I’m awake thinking the world is collapsing in on me.

I don’t have a headache, but I feel constantly sick. I was vomiting quite a lot last night, and I tried to drink water to balance it out, but it just came back up. I’ve tried twice to drink water this morning but I can’t keep it down. I daren’t try food. I suppose it won’t help that I didn’t eat anything yesterday, or the day before, but I didn’t know I was going to be drinking. I would have ate something if it was offered to me but I didn’t want to be rude in someone else’s house. Help. I never drink alcohol, I don’t like the taste. I don’t know why I did it but I’m pretty sure I’m never doing it again.
