Hi mankym - well done you - when, not if, is very positive!
I won't say I used to drink as I'm by no means a reformed character! I have, for a long time, been drinking roughly a bottle of wine a night...every night...
Before the flatshare I mentioned, I used to never drink in the week and enjoy a drink at the weekend with friends, which is my ideal really.
I've managed 2 weeks without drinking on week nights and it's made such a difference to my state of mind the morning after - I'm not pretending it's not a challenge to say no to yourself though - I keep reminding myself how much better I'll feel the next day.
I don't think everyone gets the night sweats (I'm not even sure if it's drink related but from what Jelli says it sounds like it is...).
Also, if you were a fairly easy sleeper before the drinking, chances are you'll be okay, perhaps the first few nights will be tricky. I've turned into a Kalms Sleep pusher as they've really helped me as I've always been a terrible sleeper.
Hope this helps!
Keep posting, especially when you try for a sober night, as the support on here is really brilliant!
