I drink so much coffee, and I know you drink a lot of coffee too. I think just switching from 1/2 & !/2 to skim milk (and sugar to stevia) made a big difference. It didn't take long to adjust to the change. I'm still drinking my coffee that way, and am only using 1/3 of a stevia packet now.
I didn't notice much difference in taste with free half and half, but it's full of crap… I think you were the one who pointed that out to me though.

I can easily take down a whole pizza myself, too
Aside from the pizza, it sounds like yo are eating healthy
