Drinking lots of water is good-- but what I've found works a charm is to add a tiny amount of salt to the water. On the order of a couple of very fine crystals for a tall glass. If you can taste it, you've added way too much.
Having the ions in the water helps the body absorb it more quickly, and will reduce the amount of it that gets pissed out. If I'm being responsible, I'll alternate a double with a water, followed by a water when I get home (and a b-vitamin), and another water in the morning. If I'm not being responsible (such as last night), then I basically have to play catch up all the next day.
Just be sure not to take any acetaminophen. It's hard enough on your liver as is, but if you have any alcohol still in your system it does much more damage than either one alone.
My bf says lots of green tea lol
All I know is that it works. Firsthand experience. If I alternate straight water and alcohol, I spend half the night pissing. If I alternate 'electrolyte' water and alcohol, I might go to the bathroom once before heading home. I'm seriously talking about maybe 5-8 mg of salt in a large glass of water. A 'shake' from a salt shaker is on the order of 75-100 mg. You can taste very small amounts of salt easily, so if you can taste it you've put in WAY too much-- which is detrimental for exactly the reasons that you pointed out. You don't want to drink saline, you just want to drink water with an ionic activity that's greater than 0.
caffeine also will dehydrate the shit out of you, which is about the last thing you want.
yeah but it's a vasodilator, so will lessen your headache if you drink plenty of water with it
I'm about to make a fool of myself because I'm too lazy to look it up, but I believe caffeine is a vasoconstrictor. Alcohol is a vasodilator. If caffeine were a vasodilator, then your BP would go down but caffeine increases BP.
Go ahead and slam me if I'm wrong. I'm too lazy to get my textbook lol.
