Welcome!
Good for you for wanting to try. You'll find alot of support here.
I have never been able to, or know anyone else who has been able to "go back to the way things were before" (ie, only drinking on Friday nights).
If you think you have a drinking problem, you probably do. Waking up with cold sweats when you don't drink is your body's way of telling you that it's dependent on that alcohol being poured into it - when you don't, it screams.
But the body adjusts and there's help available. Many people are scared of the thought of not ever drinking again - It's scary as hell. That's why if you focus on "just not drinking today" it's easier.
Keep posting. Keep wanting to try. A life in recovery is more of a social life than my drinking days ever gave me!
Take care ~
