It sounds like you are in the grips of needing alcohol to change the way you feel.
I can relate with that.
In the AA program we call that feeling restless, irritable, and discontent, until we can get that sense of ease and comfort that comes with drinking.
But it is a FALSE sense of ease and comfort.
Make a decision. Pick a day. Don't buy any more beer. Recovery begins with one day. You can do it.
