I´m on a keto diet, so I cannot consume even sugarless "xylitol" gums, which still have lots of carbs when you need to chew a "large bolus" of more than 10 units (like Mike Mew recommends)...And I cannot find the totally unsweet "gum base" for sale in my country.

So what I did was chewing the xylitol gums and "spit" the sweetener, but it´s too hard to keep spitting the carbohydrates FOR OVER 2 HOURS, in order to make it totally flavourless (like gum base)

I only want to use the gum for the jawline exercise, I DONT WANT TO KEEP "SPITTING" in case I needed to use new gum on a regular basis.

But I need to know what problems may arise if I keep using the same gum "over and over again", and never disposing it ????
