Right. Let’s see you drink a 12 ounce diet Coke after 6 PM and then try to sleep at night.

In my youth, I could have four cups of coffee after 6 PM and sleep just fine. Even now, an evening caffeinated beverage doesn't interfere. Different people are built different.

I drink a cup of coffee before bed to give me the strength to sleep.

See post 36. My point is that caffeine is a stimulant.

Actually, many people do indeed feel drowsy and sleepy after drinking caffeinated drinks. Why? Because caffeine messes with your sleep/wake cycle.

So to think one is able to drink caffeinated drinks late at night with no effect yet wake up the next day and drink coffee to stay awake and alert it’s just foolishness. Doesn’t work that way.
