Hey Emma!
I think that we all go through this stage! I am currently happily living off mainly hot chocolate with the occassional peanut bar or strawberry shake or tomato shake thrown in for a change.
From what vaious people have told me (I have just stuck to chocolate, I don't even think about it anymore!), your tastes will change and it might me an idea in a few weeks time to try some of the packs you didn't like at the beginning again. You may find a whole new love for them.
Also, there is always the option to mix packs. A lady in my group swears by chicken and veg together (but she can't stand chicken on its own) another lady likes thai chilli and chicken, (but doesn't like either on their own.
And with the shakes, you can always add coffee to the vanilla or chocolate!
Hope you find a way to work with the packs that won't leave you bored!
