It does get tastier, but some hate the vanilla and the soup, I don't mind any of them tbh. If you don't like certain ones, don't get them at your next wi. It's all about trying it isn't it? My favorite is the soup, chocolate and strwberry but the most popular is choc and strawberry.
Good Luck! Go bed early tonight with your water and a good book to get you through the day. Any reason for starting on a Thursday or was it, right that's it, sick of eating rubbish and threw yourself at the deep end?!!
