When you drink to any excess you dont really sleep, not in the true sense anyway. Your body is trying to mend itself, dealing with the toxins and stresses alcohol puts on our organs. It doesn't get chance to recover, hence the health issues it always causes.
After quitting, the body goes into a kind of shock stage, it doesn't know what's going on, and it doesn't like it, not one bit. It fights you, telling you it needs some alcohol. Feed me and i'll shut up, i'll let you sleep, you'll feel good I promise.
This is the one time you dont listen to your body, you tell that voice to fuck off, you do the sleepless nights and the sweaty days, you drink 4 litres of water a day. You eat fruit, you eat cake, whatever. You dont have a drink though. 3 weeks later you have the best nights sleep you"ve had for years. You sleep like a baby and you wake up feeling fantastic. This continues and not having a drink is a small price to pay for how good you feel. People can talk to you at work before 10 am, you're actually cheerful instead of the miserable **** you were when you drank. Life looks, feels, tastes and smells better.
You may have a wobble, but that will just make you stronger, more determined to beat it on your terms. At least an ambulance wont have to come, or a friend wont find you dead on the sofa. Your friends and family want you to live for as long as is humanly possible, because they love you.
Life is so so short, drink will make it shorter if we let it.
P.s. this wasn't aimed at you westy, just needed a vent.
