Shirley,

We all have trouble one time or another..don't let it get you down, we are all human.....have a great time with your houseguests, and I know you can stick with it. It is very tempting sometimes, but you can eat really great lo carb food, (and so can they) you just don't have to tell them.....if you have a chance check out some of the recipes.....good luck! You can do it!
