How long can you keep a tetra open?

Hi everyone,

I have heard different things about how long a tetra can be open, either 15 minutes (like the shakes after mixing) or all day, before you have to drink it.

I want to be able to pour the tetra into a different container in the morning (they are hardly subtle in packaging and I don't need everyone to know!) and then drink it later in the day. Is this ok???

that should be fine I take mine to work and just put in the fridge to lunchtime, the 15 mins is only for the packs, its to do with the thickening agent in them thats all, they are still ok to drink just not as nice.
