Lately, I've been having to get up in the middle of the night to urinate. Problem went away when I stopped drinking the stuff. It started as more frequent trips to the urinal during the day but I was associating it with the high volume of liquids, including D.C., I was drinking.
Now, I'm not saying Diet Coke is a bad product nor am I warning all Polkies to stay away from it. I'm just noticing a physical change and I'm modifying my behavior to fix what I see is a problem. I'll probably limit myself to 1-2 per week but for now I need to stay away from it.
