here is what i do, stumble in from the bar at 2am, grab the glass on my bed side table, fill it with water (this is a pretty big glass) drink at least one full glass full then keep it full buy my bed, if i wake up i drink at least 1/2 i always wake up feeling like a million bucks, best thing is its practically free and i dont have to walk but 3 feet from my bed at any given point in timealso i try and top that off with another full glass of water first thing in the morning
