gatorade is pretty much bad in any situation. It's just sugar water marketed as some type of hydration miracle.
Hangovers are caused by dehydration. The best way to prevent a hangover is to drink as much water as you can before bedtime. If you still wake up with a hangover, the best thing to do (in Houston) is to go get a big bowl of menudo for breakfast at La Mexicana in Montrose or Teotihuacan in the Heights.
Best hangover deterrent is weed. Wake and bake a quick bowl the morning after having drinking and I gaurentee that hangover is gone in 15 minutes or ur money back!!!!
Hey stoner, deterrent is for before the ailment. You're talking about a cure. Professional alcoholics drink a few liters of Pedialyte before bed and upon waking.
I don't know about a fistfull, but if I manage to pop a couple of ibuprofen before passing out, I can wake up and start drinking again the following day. I don't like to do this very often since it's hell on your liver though. The worst hangovers I have are when I stumble home, and straight up pass out. The best option is to force yourself to stay awake, eat something greasy like pancakes/migas/burrito/burger/chinese food and some water before going to bed. The passing out causes bad hangovers the following day. This is why I miss Austin - migas at Magnolia Cafe on South Congress at 2:30AM after getting hammered.
Completely agree about drinking water, and especially about eating Menudo Unfortunately, a lot of places don't make it unless it's the weekend. Not sure about the places you listed though.
