8-10 and Im feeling good.
14 and I should stop or Im going to get sick.
At 18 I am completely plastered, but not passed out. I can also still think and talk rationally. However, theres a hell of a hang over the next day.
The most I have ever drunk was last memorial day. I had well over a fifth. Its the only time Ive passed out and blacked out. Apparently I was cognizent enough to throw myself out of a chair and into the kitchen to throw up on the tile floor instead of carpeting. Since then Ive managed to control my drinking for the most part, Ive only been plastered once since then and haven't really drunk since that time.
