Help! I drank and now I must avoid the hangover! (Again!)

Haha Hi Reddit peeps! Long story short, I drank a good amount of whiskey this evening (I’d like to say I didn’t mean to but unfortunately, with good conscious, I cannot claim that innocence) and I have a very long and important day tomorrow. What steps can I take to make sure that I am not dying when I wake in the morning? I, fortunately, am home and I do have pedialyte in the fridge and have already eaten a decent dinner. To give backstory, when I do drink I am the type that tends to drink steadily through the day and don’t feel the alcohol at the end of the night, as it wears off, but it absolutely bites me in the ass in the morning every time. I can say that I am fully sober right now but I can 100% feel the liquor in my system and know that it will get me in the morning. What steps would you recommend I take to reduce the chances of being unbearably sick in the morning? I have tried many things over the years but I would love to hear any new tricks that you guys have tried and tested! Cheers!
