Carol,

The fat in the nuts may slow down the absorption of the sugar in the dried fruit in your lara bars. Ditto on the cheese & bananas. If you can get a non-fatty source of protein so that your sugars digest and get into your muscles more quickly, you may feel better.

This is the second time I've heard of lara bars on this board. The no sugar part appeals to me. I'll have to scope some out.
