hey guys. I did cambridge a couple of years ago. Its an excellent diet but i did struggle. Lost about a stone and a half but have put most of it back on now! Tried ww and slimming world but i lack willpower! Problem is im i started the shakes again on tuesday so am on day 3, so far so good. Im off to egypt next sunday so am planning on doing it till then and when i get back am planning on going straigh bk onto it and will follow theplan properly. Thing is im off out this saturday for a friends birthday and me and the girls havnt been out for ages so ideally i would like to drink and then sunday get bk on track agai. I know it will knock me out of ketosis but if i get straight bk on it on sunday do u think it will effect my weight loss? Ideally i wanted to lose 8 pound by next sunday! thnx for listening guys. When im bk from holiday and sticking to the diet 100% i will b a regular on here, find this website so helpful!
