Sleeping without alcohol, for me now after few weeks sober a restless 3 hr sleep at night is a 100 times better than drunken sleep
I have always had sleep problems since my early teens and I blame the whole problem on alcohol it has truly re mapped my brain , sad.
I really do not worry about sleep, if you feel like **** after no sleep or three nights no sleep that's the worst you will feel, you STILL will function ok
Do not listen to Doctors and the like telling you that you need x amount of hours sleep, they are just reading guidelines, I was a chronic insomniac and addicted to pills for seven years along with alcohol. Just let it go if you do not sleep for 1/2/3 or whatever nights , no big deal just carry on I promise you if you take this attitude you will never worry about it again.
