The half-life of caffeine is so long that even twelve hours later you’ll still have a quarter of the dose remaining in your system. If you took a 200mg dose from pre-workout (which is tame by industry standards) at 8am and you mean to sleep as late as midnight, you’ll still have well over a can of soda and close to a cup of coffee’s caffeine in your system. Imo, any negative effects on your sleep time/quality aren’t worth any benefit caffeine could bring for performance and recovery as well as quality of life. Caffeine also destroys your recovery throughout the day as it puts you in a perpetual sympathetic state.
Or if you have ADHD, you don’t have to worry about it 😂
