Chrissy consider yourself KICKED
We have all had the same thing happen to us where we fall off that wagon, and have to get motivated to get back up and hop on. I have gained and lost the same weight for the past year, on my back down for the 100th time but it is so hard. I have to look for small things to keep me going. For me it has been in the form of stickers on a calendar and new workout dvd's.
I hope you find the niche that works for you and we are here to help
