i see this a lot with people and they cover it up with uppers like caffeine.
last night i went to sleep super late and today i am up early. i feel grouchy and tired. so instead of taking an upper what i will do is run some errands and then will put on my blue blocker glasses and then grab a couple hour nap in the afternoon
now on days i don't have that luxury i will just deal with it. if i need energy i will depend on my own adrenaline, not stimulants. when your train your body for that then it isn't an issue.
