Keep an eye on your kids then - they tend to have a worse reaction to polyols than adults as their bodies don't really accept it at all. My friend's kid was on the loo all night because she stole one of Mum's sweeties.

I buy the bags of single choccies occasionally and then allow myself only one or two a day. They do have a laxative effect if you're not careful! The Vanilla Fudge bar had the worst effect on me.

The bars of plain and milk chocolate are very good for cooking, they have a lovely texture and don't cause such a drastic effect!
