This works for me, but doesnt for everyone as we all have different tastes
firstly I use more water than stated,
Vanilla shake- I make a coffee with two spoons of coffee and two sweeteners ( only have one when drinking coffee but seems to be better with two this way) I then mix my shake in a blender with the coffee, water and loads of ice, makes like a chilled latte, I also do this with the chocolate one to make a chilled mocha.
Chocolate - I make a peppermint tea, once again with two sweeteners, and whizz this in blender with the cho shake and lots of ice, very yummie choco mint
The Soup, i make pipping hot, once again in the blender so no lumps and i do add some tabasco, this isnt on the list of allowed things, and if you are worried than i wouldnt do it but has never effected my losses and i love spicy food.
I do have the flap jacks, they are hard to get down and i only find the peanut one bareable but i have it in halves, so i make a half a vanilla shake latte as above and then have half a flapjack with it, then repeat that the next day, I only have 3 or 4 flapjacks a week but just find it breaks things up a bit.
As said I didnt like the strawberry one so i dont have them.
Some people make the shakes thick like mousse, some freeze them like icecream some just get them down fast as they cant stand them, its all about finding what is right for you, I tried doing the porridge, which is half a shake made thick and microwaved til warm then crumble in half a flapjack, this i didnt much like, but others do, try things and see xx
