Heresto ~ I am rooting for you, as a mom! I am going on 60 days sober, although I started in September. The best part is being "present" for my kids....followed very closely by not being sick with hangover all the time! I feel so much better!
There is a thread here called "Class of February." I joined the September class early on, and it has been a wonderful help to me. Everyone there was going through the same thing I was and it was great to be able to talk through stuff when I felt like drinking.
Quitting is really hard at first. It gets easier and more wonderful as time progresses. So, get ready for when it gets hard and you feel like drinking. Come here to SR when you have an urge, and read...read....read. That helped me too.
Dee always says make a plan.
For me, my plan was:
1) throw away all temptation - all alcohol was chucked
2) joined September class here at SR
3) when I felt like drinking, I took my dogs for a walk. We are all in great shape!
4) told my husband that I quit and to please support my decision
5) made sure I had a soda in my hand at all parties, so no one handed me anything
6) kept ice cream on hand - break glass in case of emergency.
And when that plan didn't quite work, adjustments were made.
A plan is good. Think about making one, because white knuckling it is really hard without one.
Best of luck and welcome to SR. You'll find lots of support here.
