Personally, I enjoy a morning coffee between 7-7:30am and then arvo pick me coffee around 1:30pm. If I have caffeine post 2-3pm it tends to impact my sleep.
I have friends that can slam energy drinks post our social basketball games at 9pm and doesn't impact them.
Don't force coffee if you don't like the taste. You could try adding 0 cal sweeteners (i.e. stevia).
Lot of people aren't coffee drinks. Could also look at caffeine tablets (NoDoz), fat burner supplements with caffeine, or a moderate stim pre workout. Some of the ultra stim pre's on the market are intense, 400mg caffeine to the dome. Would set me off lol!
