My son had too much ( you have heard this all day) of much of mixed liquors last night (New Years) and @6'2" 220lbs he is very dehydrated and ill as would be expected. I have tried to get Alka Seltzer down him but he is so thirsty he keeps drinking several its of Gatorade and it interferes with him keeping it down (twice now). He is not a drinker, he uses pot which is a major issue @ home, but went out with brother and friends and too much mixing of alcohol and too much. Normally Alka Seltzer has done the trick but he doesn't want to try it again and I'm not sure if he should @ now?
