Mmm I guess it depends on how much you have to lose too, I have 10 st in total so I cant one up that quickly , I ave lost 6 .6 so far and have been noticing my thighs look abit like chicken skin hanging there, and my bingo wings could probably protect me better than a airbag, but I been told its next to impossible to have it sorted on nhs not sure if I can afford privately :/
