I have to leave the gym tomorrow by 5 am and can't use the blender that early in the morning because it will wake up my roommate. Is it ok for me to pre-mix a shake with whey, yogurt, banana tonight, and then put it in the fridge and drink it in the morning? the protein I know won't disappear or anything but it will still be high quality right? I'll prob pre-make one & refrigerate it tonight for post workout too... is that ok?
