Senior Veteran: Thank you so much for your response! Sugar, huh? That kinda makes sense. I got on a fast-food kick for a while, and I've got the pleasure of working it off now! lol The only time I drink plain water is when I'm working out, and the rest of the time I add Crystal Lite packets to my water bottle. I was wondering if that was safe to do, but I think you just answered that question. I'll cut out the added "sweetener" and see what happens. God bless you!
