HIya , good luck with tomorrow
The most important things are - glug lots of water , whenever you feel hungry have a glug , it does help distract you and fill you up a little . Distraction is very important , i always clean the house in the first few days as it keeps me busy , sleep , walk do anything not to think about food .
space your shakes out , everyone has different times they like to have their shakes , I have my first at 12 , then 6pm then 9pm , as i am normally an evening snacker , so I have something to look forward to in the evening . You can even split the packs , so you have 6 smaller shakes which can help
Like tess says , there is always somone on here that is going through that first week or just done it ( I am on day 6 now ) to give you support, advise and encouragement .
and the thing I find helps the most is positivity !! Look at this diet as a positive step towards a happy healthy life , dont dread it , dont worry about it , love it and it really helps , this diet is a head game and if you get your head in the right place it can be quite simple
as for loosing 5 stone ... when I started in november last year , I had 8 stone to loose ... I did the diet for 5 months , and lost 6.5 stone ( so your 5 stone will soon be gone ) , then I had a break for 6 months , now I am back to loose the rest .. I never thought I would get this far , but I did , and if I can then anyone can
also it does help to start a diary in the diary sticky at the top of the cambridge page
good luck and look forward to seeing how you get on
