Night Shift People Unite!

I work 12 hour shifts on nights. I work 6pm to 6 am. I've been on this shift for a few YEARS now and have put on about 30 lbs. I need to drop the weight, I have been having a hard time holding myself accountable food wise. It has been my guilty pleasure. I have a high stress job and eating is apparrently my method of coping, I'm trying to change this! I have time to snack but not time to sit down and eat a real meal at work. I am also getting married in September. I had lost about 10 lbs a few months ago but have gained most of it back. I feel like a yo-yo. I stick to counting calories for a while (and lose weight) and then I get stressed out or lazy and quit (and gain it back). I am promising myself that I will make time to sit down and have real (healthy) meals at work, and to go jogging at least 3 days a week. I would never break a promise to anyone else and I need to learn to put myself on my top priority list. I really could use some help holding myself accountable and sticking to this. If anyone else need some help as well please let me know, we could help eachother! I'm more than willing to hand out my e-mail that I can check at work to help get eachother through this! Thank you so much for listening! :)
