Hi! Welcome and good luck! I hated the milkshakes initially but they have grown on me. I always make sure I use ice cold water as I prefer them really cold. I couldn't get on with the bars or soups so just have shakes and the occassion biggest looser or tesco bar. Lots of other people really like them though so I'm sure you'll be fine.
You'll be great, you just need to get through the first few days then it gets much easier.
