NA beer is not 100% alcohol free
In the United States, beverages containing less than 0.5% alcohol by volume (ABV) were legally called non-alcoholic, according to the now-defunct Volstead Act. Because of its very low alcohol content, non-alcoholic beer may be legally sold to minors in many American states.
My Dr said a very definite NO when asked about the NA beer. I never thought about asking about a hot tub - raising the body temp. Maybe someone else has that answer.
My sides were mostly from the Ribavirin because it can cause anemia. The Sovaldi did contribute to the fatigue, but that wasn't bad until my Hmg dropped into the anemic range. Once off the meds, however, it came back up to the middle of the Normal Range quickly.
Good luck, good treating, and go get that Dragon!
