Hi Mika.
I am 57, had WLS in 1999 and went from 270 to 190 and then back up to 230.
I am following WW old momentum plan, because when they switched to Points Plus I was gaining again. I need the structure.
How are you doing now?
I too felt like a failure -

watching others that have WLS get down to be skinny... I am not going to be one of them, but I would like to be 150 and will settle for 170.
I use Android and love the WW Diary application it has a bar scanner, and does the tracking for both WW Momentum or Points Plus - and it is FREE.
Would like to keep in touch with you on this journey.
