Oh and Kirsty I have 2, I double up the water in my shakes. Because I'm finding it so hard to meet the water allowance! so I pour it into two mugs hehe lasts a little longer and not as creamy! I am going to tr and find one of those really big round hot choc mugs though so I can have it all in the same one.
The hot vanilla coffee combo is my absolute favourite as well - I save it for the weekend as a treat - I make mine quite weak as well - about 400ml or so & heaped teaspoon of coffee. I put it back in the microwave for about 40 secs so it is really hot.
Not a good idea later in the evening though - keeps me awake!
