Don't worry, he'll be far from sober and likely won't remember anything once he can get his hands on another drink. Not drinking for a day or two does not equal being sober. Not even close to thinking clearly. I would try to get out of the house and do something for yourself. Even if it's just walking around or having tea with a neighbor. If he's been drinking for a very long time, it would be a good idea to have 911 on speed dial. Alcoholic withdrawal/detox can be deadly.
