So this has potential. While I am not bursting with energy, I am not brain dead. And fitbit tells me I only slept for 5 hours and 4 minutes last night even though I was in bed for over 7, so bursting with energy is not likely even possible today.
I did use 2 scoops of protein powder in my smoothie cause I felt hungry today, probably sleep related, so my smoothie had pretty much the same number of calories as my 'normal' lunch. Interesting.
