How much do you eat?

Okay, I'm actually not kidding with this one. Latley, I have been starving ALL the time. My muscles have been really tired in workout, too. I'm certainly not overtraining - I make it 5 days/week usually, sometimes a 6th on my own, and lately it's been 4 or 5. And we aren't cranking out the yards like crazy either. I think either something is missing from my diet or I'm just not eating enough ... my guess is it's the former. Any thoughts? I eat a fair amount of protein. I constantly amaze people with just how much I do eat so I don't think it's that ...
