I have been on CD for 8 weeks now, I struggled really badly at first, but realised that a lot of my hunger was head hunger, if I really thought about it and someone had of said you can eat this plain chicken on its own, then I wouldn't have eaten it because that wasn't what I fancied.... if I had of really been hungry I would have eaten everything. After about week 3 I felt much better and no longer hungry, but I do split my 3 packs. I weigh out half a pack which is around 18g (of shake as I only have chocolate shakes) and then fill my mug up with nearly boiling water and mix the 2 together in a jug with my hand blender, then tip it back into my mug and I have a full mug of hot chocolate... I have the first half at 8am, the other half at 10.30am, then do the same with a new pack at 1pm, the 2nd half at 3.30pm and again a new pack at 6pm and the 2nd half at 8.30pm, this keeps me going all day and I dont get hungry. I also drink around 3-4 litres of water. As for the ketostix, I bought mine at the Tesco pharmacy as I was paranoid about being in ketosis, I cut mine down the middle from top to bottom with a small pair of scissors and they lasted ages, but I was never really in ketosis and haven't been ever since I started, but I have still lost loads of weight, so dont stress about ketosis (I remember someone saying this to me when I started and I couldn't believe that it wasn't soooooo important), you will still lose weight as it is a VLCD...
