Ahh hun you're doing so well don't beat yourself up. The hunger will disappear, i think although most people go into ketosis after 3/4 days, it takes longer for your body to totally adjust. I think a lot of people on here will tell you they didn't feel normal or ready to do much until week two, i know i couldn't even muster the energy to do my ironing the first week, i was flaked out in bed every night by 8.30! It will be so worth it when you get on the scales, and you're totally dealing with it the right way. You felt you really needed food so you had some, and you kept it healthy and low carb. I did exactly the same thing yesterday (have a read of my diary if you want), was just one of those days. What you didn't do was head staright down the chinese, so you should be very proud of yourself.
I think most people have two shakes/soups and a bar or three shakes/soups, but you can add a pack in or add a low carb meal in, theres no law against it, you'll still lose weight quickly, just not quite as quickly. Eating low carb whilst you wait for your packs to arrive is the right thing to do, it will mean you don't have to go back through ketosis again. xx
