Caffeine has a half-life of roughly five to six hours in most adults, meaning half the dose is still circulating that long after you take it. A 138mg capsule at 2pm leaves roughly 69mg active at 8pm. For caffeine-sensitive people the half-life runs longer still.
Poor sleep raises appetite-signalling hormones, reduces training quality, and makes deliberate food choices harder the following day. Disrupting sleep with a late stimulant dose can undo more than the stimulant contributed. This is the most common self-inflicted mistake in the category.
Take stimulant supplements in the morning, with food. If you train in the evening and want a pre-workout effect, accept that you are trading sleep for it and decide deliberately rather than by accident.
