I'm on the slower side of things - 85 pounds in about 21 months, or a long-term average of just about 1 pound per week. It hasn't been as smooth as that, though - I've had months where it went slower and months where it went quicker.
Sometimes it's maddening - mostly when other people who are losing much faster start making posts whining about how slow their loss is.

For the most part, though, I don't mind the pace. The time would have passed either way, so it's good to have spent it losing. I enjoy fine dining, and I've been able to make room in my plan for, say, one dinner a week at one of my favorite restaurants, and the occasional martini as well. I've been able to maintain when work got overwhelming for a month or two (as it is about to do again). And, I'm delighted with my new body - and I'm not even done yet.
It's a hackneyed old adage that "slow & steady wins the race" but look at that, it's really turning out to be true. I've never lost this much weight (of course, I've never had this much weight to lose...) or stayed on a plan for this long. For the first time I really feel like I've changed my habits for the long term. I'm sure it's better for me to have managed that, than to have lost twice as quickly ...
