I'm very excited for you!!
My tips are to try the following:
All the sweet ones are nice
Vanilla - you can have this hot and mix half a sachet with hot water - add it to half a cup of black coffee = latte!! (Its yum)
Of course leaves you other half to have another later too
Choc Mint/Choc - very nice hot - just like hot chocolate options or similiarst
Best of the worst for the soups in my opinion is leek and potato - the others - yeuch!!
