I have been on the pre op diet for three weeks and lost 5 kilos, was really poorly with a virus so was only eating tiny amounts, i weighed myself this week to find i had only lost 1 lb i feel so deflated and my biggest problem is when i go in hospital next week i will be on my period and i can gain anything upto a stone so all my hard work will go out of the window and i hear mr mannur is very strict if you have not lost weight. I have tried so bloody hard aswell.
