I just got a job waiting tables so I will be on my feet for 6-7 hrs at a time with no break. Not really accomodating of my eating every 2-3 hr diet. I'm wondering if there are some good mrp that come already made in a bottle I can keep in the back to drink throughout the shift or at least some protein drink. What are some good ones ya'll suggest and where's the best place to get them. Thanks for the help.
