I make coffee at home and I always have decaf beans on hand. Sometimes I just want to: a) Go through a process of making espresso (yay coffee toys^Wtools) b) Just want to drink some coffee because of its taste I eye-ball how much caffeine I consume and cut-off myself waaaay before the guideline and 10 hours before target bedtime. Given that caffeine half life is about 5 hours it works out perfectly. However, if still want coffee due to any of the reasons above - I make decaff.
