ME TOO!!! Just tonight..right now I was feeling the same way. So instead of cheating I popped open a diet coke. Now I promised myself one a day..but I am sorry, its gotta be better than turning to something with calories. I LOVE DIET COKE, so now I have splurged (cuz I had one at noon too)....
Dont know if this will help you or not...but its what I did, and right now after few sips, I know I can make it all night.
Try chugging water before making ANY decision though. It will help clear your head...really!!!! Good luck, stay strong!
