Sorry for double posting, but as long as we're getting into the nuts and bolts of it, it's time for...
A quick lesson in being a drunken fucking degenerate with Dr. Jangles:
On average, an average adult male can break down 1 serving of alcohol per hour. This is 12 oz of beer, 5 oz of wine, or 1.5 oz of 80 proof hard liquor.
When you drink a lot over a certain period of time and exceed that limit, you imbibe more quickly that your liver can break down all of your drinks, which leads to it building up in your bloodstream. This is what causes you to become drunk. During this, it will begin to affect various parts of your brain in sequence. The more you drink in a short period, the more will build up, and the further the effects will progress in your brain. First it will hit the areas that control things like social inhibition and judgement. This is why you're more outgoing and more likely to say and do stupid shit when you're fucked up. Next comes motor control and balance, this is why you're stumbling over yourself like a jackass. Memory is also affected, which is why you won't remember shit the next morning.
Last comes the nasty bits. When you hit dangerous levels (between 3.2 and 4.5 or so, depending on a number of factors including weight, sex, and what your tolerance is like) the booze will begin to affect systems that you really, really fucking need. These include the parts that keep you awake (which is why you pass out), and eventually, the parts that control unconscious functioning, including the part of your brain that tell you to keep breathing and keep your heart beating. If this happens, you're pretty fucked.
Phil is an enormous fatass, so he'll probably be fine, but since he's also a stupid fucking sped, he's probably going to ignore the big rule with drinking, which is that how bad your morning is gonna be is directly tied to how dehydrated you are. Phil is probably not pacing himself with water, so tomorrow morning should be a fun few hours of him worshiping at the porcelain altar.
