I hope you can help me with this question:

Question

"Imagine that you go to a party with a friend who starts drinking alchohol.Describe , step by step , the effects to that individual as he drinks more and more alchohol as the evening progresses and the long term cosequences that can result from alchohol consumption."
I tried to figure out the answer myself, but since I never drank nor do I have any friends who do, I was lost...
Thanks for helping!
