So, forgoing the usual goals regarding my Pepsi addiction (as they don't work), I made a new rule for myself.
I can have as much Pepsi as I want, provided I drink the equivalent amount of water first.
Hey, it's workin' for me. Far better than the whole I-can-only-have-one-a-day restriction that caused me to go through withdrawal and only think about Pepsi all day. Now I think, gee, I want a Pepsi, I chug a glass of water and help myself. Besides, usually once I start on the water, the Pepsi doesn't hold as much appeal. For which I am very thankful.
Because yes, Dad, I know it isn't good for me.
