Welcome to SR Warpa! You have our support and looking at the great input in this thread you have a lot of it
Look, you aren't happy with drinking and when you wrote this you were drinking and feeling bad about the things you won't do tomorrow because of drinking. Yet, you keep drinking. Red flag that you have a problem.
I have been there as all of us have with struggling on stopping and what to do. I struggled with it for years and while I wasted so many productive days and cancelled plans, etc., I still drank. Vicious cycle.
I agree with others on checking in with your Dr. and getting best steps for quitting. I quit, tossed out the booze and got help.
Life is amazing in sobriety and know that days that like this where you are putting off plans just because you are hungover no longer will exist.
Looking forward to the journey and the new you! Keep sharing.
