Cutting Back On Carbs

So I am giving up bread for this month and I bought this stuff called tapioca bread, which doesn't have really any ingredients you would find in real bread. It tastes ok until you get to the aftertaste. The aftertaste is really bad, or at least it is to me. If you put like peanut butter or jam on it that helps. Probably if I made a turkey sandwhich it wouldn't be as bad either. I've heard about tapioca tortillas, maybe their better. Anyway, for anyone that is thinking of cutting carbs or gluten or wheat I just want to let you know that tapioca bread has an aftertaste.
