You can do it! I would echo what the above posters said--you've simply GOT to be 100% committed to a true, lasting lifestyle change. Try remembering how good & right it feels when you KNOW you're in control, instead of the food being in control of you.
I personally think it's probably even HARDER to lose & get motivated when you're relatively close to your goal....because it's probably a bit easier to be complacent. When you're really, really overweight, you're really motivated because you just want to feel *normal*. I know I'm not quite as driven now, as I was in the first 1-2 months of this journey....but I'm holding steady & I know for sure that I've changed my lifestyle.
Hopefully something in that rambling will help!
