Hi Noladq and welcome to the forum!

You might find this link interesting and informative: http://www.lowcarb.ca/tips/tips010.html

It covers the basics on sugar alcohols. Everyone seems to react to these things differently so they're a YMMV thing that everyone has to find out for themselves. They don't affect my blood sugars at all, but for some reason too much of them tends to stall me so I keep my intake of sugar alcohols to an occasional treat. They also seem to cause intestinal upset for quite a few people so go easy on them until you know how your body will react.
