My grocery costs have gone up somewhat, but considering that I'm not hitting McDonalds for breakfast and Arby's for lunch all the time, I'm saving a lot of money there. I'm also not buying junk out of the vending machines at work...another cost savings. I have two children who are 6 and 7...too young to put on LC, but that doesn't mean that I didn't cut out most of the sugary sweets and cereals that they were eating, especially now that we are suspecting that our oldest has ADD..no more sugar for her! The LC treats are pricey, so there is increased cost there, but I just don't buy them often. My "drug" costs have actually increased a lot since I'm now taking a lot of supplements that are not covered by insurance. Worth the price, overall, for better health IMHO.
