I absolutely love coffee, and I drink it every single day — I'm also a big fan of sweet iced tea and Snapple — but I know I tend to fall asleep much faster when I cut myself off from caffeine about eight hours before I plan on going to bed. So, unless I know I'll be up late working on a tight deadline, celebrating a special occasion (like New Year's Eve), or witnessing a late-night celestial event of some kind, I try not to consume caffeine after 2 p.m.
Some experts suggest cutting yourself off even earlier — about 10 hours before bedtime — but an eight-hour window works for me. Try scaling back yourself, and continue making adjustments until you find the timeframe that feels best for you.
