Hello, and welcome.
You've found a great place, you'll find lots of sobriety here.
I got sick of the hangovers, too. I hate to think of the days I wasted laying in bed hungover.
A good thing that works for me is to think think that first drink through to the end and the misery it'll bring.
There's also support groups that can help. AA works for many.
Whatever path you choose, I wish you the best in quiting. It can be done.
Post here as often as you like, you'll find lots of support.
