Yes!! I was a diet soda addict and I went cold turkey 6 months ago and feel fantastic!! I feel healthier and the cravings are gone...now I only drink sparkling water such as San pellegrino. I know many will disagree but I think cutting out diet soda has made a huge difference. I've lost 42 lbs in the 6 months since quitting. Plus I don't like having all those chemicals in my body anyways.
