i was up on my feet and running around for non-stop for 5hrs....the first 3 hours was pure torture.i had no energy and i felt like my legs were made of lead....despite having drunk my 1/2 of shakeology right before my shift began...the next 2 hours were much better although i started feeling REALLY REALLY HUNGRY.somehow i was able to get some more energy from i dont know where....The worst thing about my day is that now that im home i really dont feel like my tummy can take the other 1/2 of shakeology....i dont feel like having anything in my mouth....even water.I had some water earlier and felt instantly nauseated....im feeling good though.....day four DONE.......DONE!
