No I have found it so easy, I only had one little craving on night 6 but didnt give in, had some calories left so had a hot choc, did the trick.
The diet is from Australia, go online and see their web page. When you buy Optislim you get a number on the packet to register for the plan. It is very good and you can record everything.
I am vegetarian so my evening meal has been some sort of Quorn product with veggies or salad. I have made soup and had that as one of my snaks along with a boiled egg and a piece of fruit. A pack of 16 shakes cost £21 from Amazon or LLyods Pharmacy, think that is the only places you can buy it. Will let you know how I get on this week.
