Hello, I was wondering why after a night of little drinking (two shots and a beer) that I am running a fever. I've never drank enough to have a hangover, and I always make sure to drink tons of water before, during, and after drinking. Is this due to the alcohol, or a virus? It might be helpful to know that I did smoke hookah for a good hour last night- could the combination of the two have something to do with my current aliment?
