Hi, Echo!
Wow, I don't know if there's any way to "stop" losing weight in one spot, but I have read several responses back from Maintainers who say that once they settled at goal for a while, the angular edges tended to round off. I have some fairly severe angles in my face that are coming back now (gee, I remember cheekbones!). Not sure if we share similar builds or not, but when I got to the weight you're at now, each pound started to make a radical difference.
Re the other question about how to take off the last 10 pounds - this is definitely the right thread! I can't answer that one yet since I'm in the same place you are, but you might want to consider posting it over on Maintainers. Many, many people seem to end up losing more while they're trying to figure out their maintenance calorie level.
