Depends on the situation. I had 10 shots the other night but I was so stressed out worrying about a couple girls I was with who drank way too much that I didn't even feel the alcohol until I had gotten everyone home safe and I was back at my dorm room. I don't usually black out until 15-ish drinks. It depends a lot on how much food I've had too. [Edited on 11.15.2012 10:48 PM PST]
