Yay congrats! I had to pay £20 so £10 is good!
You will quickly work out what you like and wht you dont! I went for flavours that I knew I likd to begin with, chocolate is a pretty safe bet! but once you know what you like then you can get one sachet of something else the following week, try it and then if you like it you're a winner! by doing this I have recently got a taste for strawberry shakes and veg soup! I'm really lucky, I like the porridge (just maple and pecan) three different shakes, chocolate, choc mint and strawberry and three different soups, leek and potatoe, tomato and veg, I do only like the choc tetras though, all the other ready made ones taste funny to me!
More than anything just make sure you keep putting away that water! If it helps get some flavouring, I like the summer berry one, yum yum!
Good luck to you!!!
