I am finding myself without any time in the day to make my shakes.. I tried making one this afternoon in the car with a half bottle of water, and ended up with french vanilla powder all over me and the car..
so my question is.. how long do these things keep when premade and stuck in the fridge? I have access to a fridge all day. So I would love to premix half a dozen shakes or so and leave them in the fridge to grab in the morning otw out the door.
(I realize there are RTDs, but my DH and I are broke university students, every penny saved counts.)
Thanks
