Hi Robin! I'm glad I am not the only one with this problem! I've been on Atkins for 3 months now, and like you drank Mt. Dew all day, only I drank diet. I know it's considered a no-no, but I STILL drink it (only now it's diet Code Red). I haven't experienced any stalls so far but I know in some aspartame induces cravings, stalls etc... Anyways, good luck!
