60 lbs is so great!!!
you say it is only the tip of the iceberg, but in my experience, you should pat yourself on the back strongly for doing this...
i know from my experience, with so much to lose (130 lbs at least), that when i lose 40 lbs or so, i don't love myself enough to see this as a great achievement...WHAT HAPPENS THEN IS-- IT BECOMES EASY TO GAIN THIS RIGHT BACK!
so, keep on with it, no matter how long it takes....me, I am starting AGAIN! but this time i will keep losing until it's all gone
all good things to all of you!
