I have had an addiction to sugar free gum in the past. I have also known other people (my cousin, my sister) with similar obsessive personalities to have the same problem. My sister even talked to her therapist and nutritionist about it and it is a real condition i guess. ocd. i would chew through 3 plenti-packs of extra sugar free gum per work day (less than 8 hours). I would feind for my gum when I didnt have it. very obsessive. I eventually got over it. Sometimes the sweeteners did make my tummy hurt too.
