Did you stay on the wagon? I stumbled on your posts and I relate to you tremendously. I've always had a dangerous relationship with food. To keep the story very short, I gained over 100 pounds when I was in a really bad time in my life, drowned myself in academia and food, lost 80 pounds, was tremendously happy and in a fantastic relationship, got married, finished my Ph.D. (all the while, gaining 50+ pounds back...), and here I am. Congrats on your successes and persistence. I don't know about you, but it's an interesting challenge to work on my health and body now that I can't distract myself with "having too much to do right now."
Willpower is remembering what you really want.
Get back up and finish what you started.
