I'm English, and from the north, so when I went out I drank just about everything. I drank if it was awful tasting, and when I had one pint down me, I had to drink until I passed out due to my lack of self control. 3 days ago however, I quit drinking, and I'm quite happy about it.
When you wake up outside a bus station 10 miles away from your own home at half 5 in the morning with a wet patch, no shoes and shirt, vomit in your hair and a banging headache, your mind kind of gives you a hint you're not the type of person that should be drinking.
PS. That was about 1 year ago, and surprisingly didn't end drinking at that point.
