No I'm not. I wouldn't say it's an easy day but you can get through it knowing the next day you can eat what you like keeps you going. Also on CD all other food is banned but on JUDDD you can have a snack if you want. If you wanted you could have e.g
B: Shake (110) If I remember rightly?
Snack: Apple (70)
L: Shake (110)
snack: Babybel light (40)
D: Shake (110)
Snack: mini chocolate twister ice cream (40)
So the total calories is only 480.
You just need to watch any milk in your drinks too.
