You're putting yourself in a situation where you'll be alone with a heavy drinker with no escape for 1 or 2 months?
I've caved after one night in similar situations.
Your addiction is doing somersaults of delight right now man. It's waiting for you to cave.
Its a shame you can't see that.
The stay at home thing is not a suggestion for you NY guys.
This is an adult problem that needs an adult response.
Stay home and take care of your mom, NB
