I've lost almost a stone too and I can't notice. My hubbie said he noticed that my back boobs were getting smaller and my son said my actual boobs were now bigger than my belly, so they've clearly noticed some difference!!! Charming, aren't they? Anyway, I'm thinking it will start to be more noticeable after about 2 stones. My clothes don't even feel looser or anything! But we will just keep going and one day, we will be thin! Hip hip hooray!
