Last night I found myself low on calories- like unacceptably low. After exercise, I had a protein shake made with 100 cal designer whey protien. Other than the fact that it is a lot of chemicals.... It looks ok for P1 and it is quite tasty.

2g sugars (which I think come from the chocolate flavors)
Thoughts? Good, bad? Ok after a strenuous workout? This has been the lowest cal protein mix i've found.
