Sleeping alot
If you aren't getting enough protein you most definatly will be lacking in energy and sleeping a lot. I was very bad at getting my protein this last summer and I slept most of the summer away, as well as almost passing out because I was so weak. Please Please take my advice and get all that protein in. There really is a reason they have you take it. It took me a long time to find some I liked. But once I did things have improved tremendously. Not that you don't need blood work also, you could be low in iron or Vit B also. I just am sharing what happened with me. Good luck. Cindy G.
