WOW - what a phenomenal transformation! That's a heck of an achievement and you should be very proud of what you've achieved!
I'm concerned about maintaining too (once I reach target of course) but I think as long as I keep going to class (kind of my conscience) then I should be ok. That and reminding myself how good I feel now compared to a year ago.
Wow, that's an incredible achievement, really well done! You look beautiful in the first picture, but in the second... it's a complete transformation! You look even more beautiful, and healthy and confident. You really do look like a different person. Congratulations and good luck with the maintenance!
