Hi Ridler, welcome!

As Lisa says, sugar alcohols (maltitol etc) can be a problem for many people. Some of also have issues with the laxative effect and bellyaches they produce!

Have a look at "Low Carb Tips" on the orange bar at the top of the screen. Doreen T has written a great article there explaining the ins and outs of sugar alcohols.

Cheers.
