question about protein drinks

My DH will be out of town all next week, so I thought that I would try doing some pure liquid days or a few meals.  Does anyone know if I can make up protein drinks in advance to keep in the fridge for an extended period of time.  Do you think that they would ge****ery? 

Thanks!
Deb

I haven't had any luck with that.  I think it depends on the protein powder you use.  Try one and see how it holds. 

I'd say no more than a day... but why not get the pre-fab ones, like EAS Myoplex or slim fast optima?

Deb,
EAS Myoplex in high in calorie and carbs.  I use EAS AdvantEdge Carb Control. They come in Vanilla, Chocolate, & Strawberry.
