I have a friend that seems to have a big problem with drinking. Last time I saw them they had been out for lunch with friends, had a couple of drinks but had then gone home and drunk half a bottle of vodka. They were full of remorse the next day but said something that had stuck with me which was they knew they had a problem but didn't know who they would be if they didn't drink.
I don't drink very much and if I have more than 3 I feel really ill so rarely have more than that. I don't really understand thier statement - does this make sense to anyone?
