Hydra, I went through the same thing. 25#s, and only in the last week has anybody said anything. It is aggravating, and a little discouraging, but you can't let it get you down. For me, a lot of it was that I was wearing clothes that were too snug when I started losing (and I'd accumulated a lot of shapeless sweaters as well), so I was still just wearing the same stuff. It wasn't until I started digging out some different clothes, that actually fit, that people started to notice.
The changes you're making are tremendous in terms of your long-term health. When you feel good, it radiates ... and people WILL notice.
