I took your question straight to the experts at the rootbeer marketing board, and they say your symptoms are most likely the result of a rootbeer difficiency.

they suggest you drink 2-3 gallons of rootbeer a day and take 'rootbeer baths' to eliminate (or at least minimize) chaffing. If you still experience problems you may need to add red licorice to your diet and watch more TV. Hope this helps!
