On Fridays and Saturday nights, I always feel that I should be going out and living it up. I'm well aware that I can't do that like normal people, so I stay away from the nightlife. However, it still leaves me with that feeling that I want to be out partying with friends. If it's a party night, I've turned to rewarding myself in other ways in order to stay sober. Usually i'm alone so I treat myself to eating out. This includes ordering food to go. As a result, I dont feel guilty for eating out, and I stay sober for another night.
My suggestion would be to treat yourself to room service and order yourself a movie.
