We are the same height and when I reached the 160's I hit a plateau as well. It was all fine and good until I got into the low 140's. But I was better with the stall at 140 than I was when I was 160+. Congratulations on getting past the plateau and another congratulations on the health benefits that came along with it!
Awesome job so far and
KUDOS to you for waiting it out and not giving up. That, in my opinion, is your biggest success!!
WTG!
