How long...

How long was it before you actually felt/saw a difference in your clothes/waistline etc. theres a parent on the school playground who has done so well with slimming world, every week i saw her shed lost more and more weight and she really does look amazing for it! I know us ourselves dont see the loss that great when we look in the mirror, its mainly others who see it. But when was it you could actually tell the difference?
