Hi Minniemooo
I was the same as you on day one, my first packs were original porridge and banana shake and I was ready to give up I thought they were so horrible!
I guess everyones tastes are different, some people love the shakes and others hate them. I live mainly on soups now (tomato and oriental chilli are my favourites) but I do have the occasional shake - mango and fruits of the forest are the only ones I like. I make them up with more water than recommended and add loads of crushed ice, then mix to a slushy consistency with an electric hand blender. I find ice cold slushy consistency much nicer than normal shake made as per the instructions. Do persevere though, I'm sure you'll find something you like and it will be worth it.
