Soda has been the worst for me but I bought some sugar free drink mix and I have increased my water. I am a coffee drinker too and I like my caffeine so not sure if I want to try decaf. I just might have to stop cold turkey. My doctor only does a 4 day liquid diet that is when I will drop everything that I am supposed to whether I want to or not. I want to be successful at this and I will be. Thinking positive will help get me through. I am just a nervous wreck is all about all of especially the surgery. Come on May 19th !!
