My wife swears by the Liquid IV packets. She drinks one in the morning and every night before bed at TTR and never wakes up with a hangover.
We couldn't find liquid IV at a reasonable price in Canada last time around so we bought some Vega Sport Hydrator packets and some Hydralyte tabs. For us, it worked wonders. One packet mixed in one bottle of water every night before heading out to Bash, one when we came back from partying and one when we woke up the next morning. Overkill some will say but we never felt hung over and were always up for a drink (and some more hehe).
We take Lyteshow before we start our night and usually the next morning and it helps a lot... https://www.amazon.com/LyteShow-Ele...keywords=hangover cure&qid=1613409190&sr=8-49
We tried most of the major brands. I didn't notice any real difference from one to to the other. I think the biggest thing is find one that is palatable to you. Drink and much as you can of it before you you go to bed and when you wake up. If a product isn't palatable your less likely to consume the water that goes along with it. All the stuff has electrolytes and other trace ingredients in it but its all about hydration. Also if you wake up and feel sluggish get your butt up. Eat something real light and do some activity that gets you sweating. Getting that heart pumping helps burn off the fog. Follow that with some unhealthy calories (screw that healthy crap, you already drank all night), hit the sexy pool then wash rinse and repeat until check out. It works for us
Like others have said, all the products are generally about hydration and the one u will acrually use is best. One extra routine we have is that at each meal we go to while there, we each order a Suero. It's essentially soda, salt and lime.
