Lately I've been experiencing a persistent "foggy" feeling. It hasn't affected training too significantly - once I'm warmed up, it's usually not as severe, and my lifts haven't taken a toll either - but it has interfered with my ability to focus.
I usually sleep around 8-10 hours a night, and eat an average of 3,500 cals at 6'0 and 190 morning bodyweight.
I am also a coffee drinker - anywhere from 1-4 cups a day. How might this be involved?
On a side note, I have also noticed I am more quickly to shortness of breath when I'm in the gym.
Sorry if this isn't the most clear post...I'm not feeling terribly articulate today. All replies are appreciated.
