islay,
use these people www.forerunnershealthcare.com i used them 6 years ago. i got a gastric sleeve op in mumbai india, doctors there are best in the world. i paid £5000 for it then but i think they are charging only £4000 now for same op.
i was depressed with my wieght back then and now if i was not drinking beer i would be like a stick insect, beer is the only thing keeps me from getting too skinny, im sitting at around 80kg now as before i was 117 kg.
i will never look back and advise anyone to get the op.
PS. shop around for surgeons in india as you may get cheaper.
