Have sent you one via trust if you haven't already got one.
Tried this out for three days, was intending on just using it for breakfast as I struggle making and eating anything for breakfast. Was very surprised as it's not only nice, I can easily drink the whole thing and I'm still full by dinner time, at least.
Haven't tried them all, but for me vanilla plus a little of the flavour boosts have been my favourite and I'll probably stick to those. Caramel / Toffee / Banana. Not tried the tea / coffee ones but I can't imagine is like them. Still working my way through the flavours though so might find something nicer.
The 10 samples are only £1.50 on your first order, so it's cheap enough just to give them a shot and then make your mind up.
