174.2 today, still in that range (it's got a vice grip on me).
Stripes, I am so with you! All I've been doing is up, down, up, down, up! I'm starting to hate th 170s with a fiery, burning passion. Let's hold off on removing digits for a while, though.
I think disappointments can be acknowledge as well. It's part of the whole thing. Our weight will go up, or stall, for one reason or another. It's normal and expected, and we all have it happen. I've been around my current weight for approximately 17 years so far.
Maui, I'm in the mid-decade dance and I hate it, too. Probably not as bad as the end of a decade, because I'm pretty sure I can't even see the 160s from where I'm sitting (still in the same old range).
