I found myself thinking and doing the same. I achieved my goal for my wedding in November and rocked that dress like I didn’t think I ever would. I saw a hope for abs and I got comfortable and it started to slide. And now I am at the point where I am putting weight back on and starting to get uncomfortable again and I am kicking myself.
I have a theory that our bodies will let us mess around just so much. Then they have a way of self-preservation. Getting out side or beyond that limit is when it gets tough. And even if we do make it there, our body will never give up trying to get us back to that safety zone. I found something really scholarly on this subject just recently, but damned if I can find it now.
Anyway . . . wishing you success on attaining your goals, whatever they may be!
