Caffeine and sleep answer
A peer-reviewed Geebs Science answer on caffeine timing, pre-workout, sleep quality, recovery, and why a cutoff is worth testing before adding supplements.
Short answer
Caffeine before bed can hurt sleep for enough people that it deserves a real audit, especially if late training, pre-workout, or afternoon coffee keeps showing up before bad sleep. The coaching move is not panic; it is testing timing, dose, and consistency.
Practical move
Pick a caffeine cutoff for seven nights, keep the dose stable, and watch sleep timing, wake-ups, next-day cravings, and training quality before changing anything else.

Peer-reviewed source trail
For clients using pre-workout late, the first recovery fix may be a caffeine cutoff, not a new sleep supplement.
A shutdown routine is not soft advice; it protects the next day's training quality, hunger control, and decision-making.
Give clients one concrete sleep behavior, not a 14-step protocol: phone away from bed for a fixed window.
The easiest sleep upgrade for a busy client is often environmental: keep the phone out of bed before trying to optimize supplements.

FAQ
There is no universal cutoff. A practical starting test is moving caffeine earlier, especially if sleep timing or wake-ups are already a problem.
Yes if it contains caffeine or other stimulants. Late pre-workout can be the hidden sleep variable in a program that otherwise looks solid.
Not automatically. Most clients need a timing and dose audit before they need a total ban.
More Sleep questions
Sleep and cravings answer
Poor sleep does not guarantee cravings, but sleep restriction can make appetite, snack intake, training quality, and decisions harder to control. The useful coaching move is to audit the sleep pattern before treating late-night cravings like a character flaw.
Phone and sleep answer
Phone use in bed is not neutral for many people. It can keep the brain engaged, expose you to light at the wrong time, and push sleep later. The useful coaching move is not a perfect evening routine; it is getting the phone out of the bed environment first.
