Hiya hun
Yes I've tried the flapjack and the chicken soup too.
Honestly I don't like any of the products but what I do is for strawberry and vanilla, I mix it with about 400ml of water ( I know it's more than recommended) and I put ice cubes in the blender too! I found that this way it lessens the strong taste of the shakes. Lol
With chocolate, I also mix that with 400ml of water and I add peppermint tea to it too! And this I drink hot
Chicken soup again I mix that with 400ml of water and drink it hot! ( I have to have this because it's savoury and I'm kinda getting fed up of all the sweet shakes)
As for the flapjacks! Hmmm what can I say they are utterly disgusting. I almost puked on them! However I do think u should get 1 and try it, u never know u might like it!
Good luck for your weigh in! Let me know how it goes
