I too 'had' a soda addiction. Diet PEPSI is my drink of choice. I was such an addict, that if I traveled anywhere, especially the south, I made sure to have my own DP, since coke was more availalbe.
But last week, when I committed to this change, I realized that if I am going to do this, I'm gonna do it ALL THE WAY. Once the band is on, burping/hiccuping can actually 'possibly' move your band. And once your stomach is reduced, the amount of space is too limited for the 'fizz' to die down. Today is day 6 and I'm doing fine. Now day 1-3, those were a bit hard. I had such a 'ritual'. But now I bust open a bottle Water and add my crstal light. You can do it. Especially if I can.
GOOD LUCK!!!
