i started using a variety of different shakes, soups bars etc but 2 weeks ago i realised that no matter what i have i always wish it had been a chocolate tetra so decided to go on choc tetra only and have actually found the plan much easier to stick to having only chocolate tetras. i think its a combination of the ease of just grabbing one ( not having to blend or anything or hang around in the kitchen) and also the fact that there is no deciding which flavour to pick this time.
i do have a few bars in as well incase i fancy something to chew on but so far im happy just sipping on the tetras.
