The best times to drink black coffee is between the hours of 10:00 a.m. and 12:00 PM, and between 2:00 p.m. and 5:00 p.m.
If you drink coffee and have trouble sleeping you should stop drinking coffee within 2 to 3 hours before bed so that the caffeine in the coffee has time to leave your body.
The caffeine can keep you awake and make insomnia worse.
I always have to stop drinking coffee at least 3 hours before bed or I will not get any sleep at all because the coffee keeps me wide awake.
Even if I take sleeping pills the coffee still keeps me wide awake so I always have to avoid coffee 3 hours or longer before bed.
I drink more coffee in the cold winter months than I do in the summer months but I still drink coffee everyday regardless if it's cold or hot out.
