Sounds like we've had similar losses, I've gone from a 22 to an 18 too. However can't even get size 16 jeans up let alone done up. Seems to be a much bigger jump. It feels good getting into smaller clothes though doesn't it.
I need to get my size 24 bridesmaid dress for November taken in at least 3 sizes and I'm so chuffed.
These are the things that will keep us going.
