  1. Let’s approach this scientifically. The half life of caffeine is 6 hours on the high end. The affects of a substance diminish at about 1.5x the half life. So, stop drinking coffee at LEAST 9 hours before bed.
    Granted there’s variety of factors based on the individual that I won’t go into, but that’s the most basic universal truth. I stop drinking caffeine at about 2pm if I’m planning on going to sleep by 11pm or midnight.

  2. Q: “How many hours before bed should you stop drinking coffee?”
    It depends on your metabolism. Caffeine can stay in your system anywhere from 2 to 6 hours, so you need to determine for yourself when you should avoid any caffeinated drinks, but just coffee but sodas as well.

  3. 6 hours according to research published in the Journal of Clinical Sleep Medicine.
    RESULTS:
    Results demonstrated a moderate dose of caffeine at bedtime, 3 hours prior to bedtime, or 6 hours prior to bedtime each have significant effects on sleep disturbance relative to placebo (p < 0.05 for all).
    CONCLUSION:
    The magnitude of reduction in total sleep time suggests that caffeine taken 6 hours before bedtime has important disruptive effects on sleep and provides empirical support for sleep hygiene recommendations to refrain from substantial caffeine use for a minimum of 6 hours prior to bedtime.

  4. I have read anywhere between two to six hours. I guess a lot depends on the individual. I can drink a cup of coffee and go to bed just 30 minutes later. I drink, on average, 2–3 cups a day and sometimes less. Also I take magnesium which helps to relax my nerves, so maybe caffeine does not affect me as much as others.

  5. It depends on the concentration of the coffee and your sensitivity to the caffeine. For me, having a weak typical Norwegian coffee 2–3 hours before bed doesn’t disturb my sleep. But, if I take a strong coffee I need 4–5 hours of gap to fall to sleep. As I have consumed coffee for a long time, its effect is not as strong as it used to be.
    If you are a beginner, and taking strong coffee, it is recommended to to stop drinking it 6 hours before bed.

  6. I have read somewhere that one should avoid consuming caffeine as from around 2pm, or at least seven hours before bedtime. Coffee does have a negative impact on your sleep. It contains nicotine which triggers insomnia in many people. If you are highly sensitive to the stimulant, you might consider cutting it out earlier.

  7. The half-life of caffeine in humans is 4–6 hours. If you’re planning on going to bed at say, 10 PM, without any issues I would limit your caffeine intake before 6 PM at least.
