I did mean to combine the tablet with two litres of water because normally I do drink two litres before bed and I still have a hangover
As I mentioned, water doesn't really work. You don't need to take my word for this, but just know I drank a lot before quiting entirely. When I say a lot, I mean, 2-3 bottles of vodka a day was fairly common, hangovers were every day life.
My experience taught me that having a big breakfast with lots of fat and protien reduces the effects of a hangover faster than anything, so try a full english breakfast in the morning.
The other thing is your hangover will be worse depending on what you drink, I always found for myself that red wine was bad, also certain beers, Stella artois being one. Mixing drinks also massively increases hangovers, so stick to one type of drink for the night.
Alcohol disrupts your sleep cycle, and usualy sessions on the drink mean you staying up later than normal, so you get less sleep which is also of a poorer quality.
If your planning on ways to mitigate a hangover so that you can keep drinking, I'd say watch that, you could be suseptable to alcoholism, something thats on you before you know it, and is an extremely nasty and painful life to live.
Like I said before, the only way to avoid a hangover is abstinence.
I started drinking when I was about 14, I am now 52, I have not had a drink for four years. Every bad choice I ever made was due to booze. Just be careful out there, love your life, don't chase the high because that rabbit hole has no bottom.
