Mkendrick, I know that you have lots of life changes coming up but you can definitely maintain. I still cook great meals for myself and DH, not always baked chicken breasts. Like another poster said, I just figure out how much I can eat of some things and have carefully planned go to recipes. I imagine that soon to be DH will appreciate the food if it keeps the happier, more vibrant and sexy you around. (Not that you weren't sexy or vibrant before by any means, just saying that your posts scream how confident you feel and how happy you are with your look now. I know that I am after my loss and exercise shaping, so I radiate sexy so much more than I used to, if I'm projecting me onto you I'm sorry.

I worry that you are looking at your upcoming life changes and have already decided that you are going to fail and are looking for excuses? Someone on here has a signature 'if you fail to plan you plan to fail'. You have done such a great job and look fantastic. You can absolutely make a plan to survive the life changes and come out on top.
If I could give one piece of advice it would be to start to make your plans now so you can survive. You didn't just diet, you changed your life. This is a perfect time to make plans for the other changes coming in your life.
I know this isn't what you asked, but it has been weighing on me since I read your first post and you have been in my mind. Again, not trying to offend and sorry if I did.
I did lose and regain over and over in my past as well, including losing before my first wedding and then putting the weight plus some back on in the next couple of years, losing after I got divorced, regaining plus some, losing when I met now DH, regaining after he and I got married, and now maintaining with a happier life, better diet, tons of exercise.... If I could do it again I would change so many things, but it would all come back to planning and better choices.
