Flat Pop OK?

Is there any way that totally flat pop w/ 0 sugar 0 salt 0 caffein can hurt me? They say no carbonated beverages but if it's flat it's not carbonated. I want to mix diet cream soda/chocolate soda with my protein shake for better taste.

I can't think of any reason why it would. As long as you don't count it towards your water intake it should be fine. p.s. i heard you can blend soda in a blender and it gets rid of the carbonation so you don't have to wait for it to go flat. all my best, Amy

It's actually on my OK to drink list from the beginning. My directions say open the can, and put in fridge overnight. Enjoy! HUGS Kimberly
