I'm so sorry to hear your news, Bri. 3 pints is a LOT. I used to drink 2 pints and that would keep me pretty snockered. Drinking to that degree is very spooky. The trouble with alcohol is that you'll drink when things are bad, you'll drink when things are great, you'll drink because the sun came up this morning. I've drank for all those reasons and many more.
I forget if you go to AA. They have helped me tremendously.
Please take care of yourself and concentrate on the next sober 24 hours - just one foot in front of the other.
I hope you didn't end up with some lasting legal problem. No DUI or anything?
