Ok Ga Gang....HELP!!!!!!!!!!!!!!!

I had RNY on Feb.2 2005. I am over two years out. My weight at present is 195-200 depending on what time of day I weigh. I need motivation to start exercising and focusing on my health again. I would like for any nurses out there who have also had RNY to respond, although any responses are welcome. I have been a nurse now since Feb. and work in an LTC facility. Any of you out there who also work in this type of facility know that it is busy, but also gives a certain amount of slow time. I work all three shifts, so my sleep cycle is screwed leaving me without a lot of energy. Please help me with this if you can. Snacking has become an issue again. I never want to return to the state of health I was in before. I am really scared. Thanks so much!!! Tonya
