Congrats on your 100 lb. loss Starbrite, that is such an accomplishment. Like you I'm trying to keep focusing on the positives of what I've done and chip away at what I want to get off.
I weigh everyday, the fluctuations don't bother me anymore, I've tried to train myself to compare week to week rather than day to day, it's my way of acknowledging that I'm at least going to attempt to be on program. I know from my past behavior if I don't weigh in I start to slip away from my program. So that's just me, everyone's different.
Again, congrats and thanks for sharing your renewed journey!
Best to you
