My days are so busy and much of them are spent on the road. I need a pre made canned protein drink to get me through the busiest part of the day. It needs to be high in protein and low in sugar so I don't get an afternoon slump. Does anybody have any suggestions for me? It would be nice if it tasted good but it doesn't have to. I just need a lunch meal replacement so I don't grab whatever is around as I rush from class to class with my kids.
