Can I pre-make powdered shakes

Hello, Tomorrow is my first day at work on the pre-op liquid diet. I don't like the shakes in the can. I have been using slimfast powdered mix with ice and milk.  Am I able to premake 2 shakes and put them in a thermos. I thought I read on the board a while back is it not good to pre-make them. Any night owls on tonight that may know? Thanks

I went to dollar store and purchased  children sip containers. They hold 8 ounces and I got 6. I would make 3 a day and have them in fridge. When they were in dishwasher I would use other 3. I just shake them before I drink. I would prepare in blender and than empty into 3 containers. If i was lazy I would bring the slimfast premade shakes. I keep them cold with freezer packs in my lunch bag. Pj

I 've read that  the protein powders decompose if pre-mixed, so it should be mixed when you're ready to use it. Not sure if ALL do. Sandy R

Yes - I too heard that you can lose to effectivness when pre mixing protein drinks - but I did it anyways - because it was such a hassle to mix at work! I made it through just fine! LOL I pre mixed the three or four that I would take to work with me...

When I was on full liquids immediately post-op and had to be away from home for several hours I made protein shakes and took them in a stainless steel thermos.  It seemed to separate a little but was still good and served its purpose.  I would at least try. Wishing you the best, Cassandra

At GNC they sell a tiny battery operated mixer for $10, I use it every day. You can keep your protein powder at work, and just bring your milk in the cooler. You should not pre-mix your protein drinks ahead of time
