I'd think the malitol would cause problems if it gave you diareah. Kind of like when my friend told me she took a huge thing of caster oil to induce labor. It gave her diareah and the cramps form that set of labor. My only thought was that would be the absolute worse time to have bowl problems

I agree ask your doctor and ger his/her opinion. You might also do some studying on your own. Just be sure if you find an article on the dangers that it is backed by sound scientific study. There are so many scare articles out there it's rediculous.

You might also find that you can cure your sweet tooth with fruits. Maybe instead of going to Dairy Queen have a fruit parfet with homade whipped cream. That or get some plain whole milk yogurt and mix in fruits for a sweet treat.
