I used to weigh once a week and found the suspense was killing me. If things turned out ok, I was fine, but if I STS or went up, I was devastated. Especially if I felt I had done ok. Once a week was just too stressful.
I recently started daily weighing. First thing in the morning, after a bathroom visit and (cover the kids' eyes)
sans garments, if you get my drift

. I'm weighing me and only me. Suddenly, I'm feeling empowered. I feel like I'm in control here.
It's only been a fcouple weeks and I have yet to encounter TOM (but I suspect it's right around the corner), but the little daily halfers up and down haven't thrown me for a loop at all.
I think this way is going to work for me.
