A couple of years ago I went to the doctor and I had constant stomach and digestion problems. I was also on the way to being extremely overweight like the rest of my family. The doctor says: You are drinking way too much pop and it is ruining your system. I suggest you stop - or the problem will keep on coming! So I did, I just stopped! Call it an allergy, call it whatever you want there is NOTHING good for you in soda! So if it isn't good at all for you - Just STOP taking it!
I have not been drinking pop in over 10 years! And although I am overweight, I am still the skinniest one in my family!
