Hi NewMe (from another NewMe):
This alcoholism thing is really hard to handle all alone. Can you find a meeting (AA, SMART, etc.) nearby that you could go to?
The problem, as others have stated, with planning to stop tomorrow, is that one can always make that argument. In the end, the only thing you can impact is right now.
So, try to stop drinking right now. Find a group of alcoholics that you can talk to or chat on SR or post more.
I found that asking for help from others felt strange at first, until I realized that I was helping them stay sober. So, reach out. We all want to help.
