Lynne, I can't believe you gained with the prep for your colonoscopy. Sounds like it does run in your family though. I was wondering how many calories you are allowing yourself each day. Maybe your body has gone into starvation mode. You probably don't want to hear this but I lost 5 lbs with my prep. Right after that I started the Daniel Plan 10 day cleanse and lost another 5 lbs in 10 days. That's why I had such a good loss for December. As soon as I added dairy and grains back my weight loss slowed way down.
