Oh poor you, the first day is always the hardest because its when you miss food the most. Try to do something that will take your mind off it, ironing, cleaning, having a bath, anything, also try to stay out of the kitchen and avoid preparing and cooking food if you can. It is hard but try to take it hour by hour and remember that every hour is another achievement. Have an early night .. that always helps me but most of all stay strong and motivated. This diet is brill and I am a slow loser on any other diet but have managed to lose 20 pounds in 5 weeks.
Good luck x
