I used to drink 1-2 diet sodas a day and just a little while ago my stomach started bothering me shortly after I drank them. I stopped drinking them and now I feel much better. I tried a little sip of one the other day and I did not like the taste at all. I have not had one in about 1 month. I have also noticed that I am sleeping much better. I used to wake up several times during the night and I always had a hard time falling asleep. I am not sure if no longer drinking the sodas has helped with my sleeping but it sure is nice to sleep through the night.
