JWN, Oh yes teenagers! DD2 has not yet grasped that laying in her bed until lunch-time then getting up to watch 5 episodes of Come Dine With Me is not a very good strategy for getting a job.
Clear-head, read any of the posts on here from people who have been sober 6 months, 11 months, 6 weeks, 7 days, 2 days, whatever.. and you will see that if they have given in to the voice that says "oh go on", the result is not pretty. They get pissed, feel crap, feel remourseful, feel guilty, feel hungover, realise once again the awfulness of being an alcoholic who ccan not seem to drink in moderation.
Don't worry now about not drinking at the weekend, concentrate on how good you feel today, now. And as others have said, if you want a drink, go right ahead, and see what happens.
One of my favourite ways of fooling myself was to not drink for a couple of days (so I KNEW I wasn't an alcoholic), then have just one drink. After that one drink, I knew I was fine, and could have stopped if I'd wanted to, so it was OK for me to have another. After the second glass, I felt fine, and could have stopped easily if I'd wanted to, so I gave myself permission to have another drink. And so on until the end of the bottle, when I'd be saying, Oh no, I have a problem, I can't stop, I want another one. I NEVER chose to stop after just one drink (even though of course I could have, if I'd wanted to 
).
Have a good day everyone. See you later.
