Sometimes I drink some pop before bed to keep my mind semi active while asleep. It helps me have LDs, sometimes. I was just wondering how long it will stay in my system. I am 120 pounds, 5 foot 9.

3-6 hours usually seems the average but it depends on how much you drink and it varies individually.
The effects of caffeine can last a good while. A cup of coffee at 4:00pm, and I'll still have insomnia by midnight when trying to sleep.

The time it takes for the body to eliminate one half of a caffeine dose is normally between 3 to 12 hours. It is called the half-life of caffeine. Several factors can shorten or lengthen the half life of caffeine. Smoking, medications and diseases are some factors. Pregnant women have higher caffeine half-life, 18 to 20 hours - pretty much longer for the fetus since its organs are not yet fully formed to be able to eliminate caffeine easily. About 99% of the elimination process takes place in the liver.
It varies, but for most people, a single shot of coffee can stay in the system for 6-12 hours, or longer. In small doses, though, it can *theoretically* keep the conscious mind awake a bit more while the rest of the body goes to sleep.
Hey, Jeff, you updated your avatar!
The more melatonin in your system (at night), the slower your metabolism. That's why a cup of coffee in the morning only will wire you for like 2 hours, but why exo's 4 o'clock coffee keeps him up.
If I drink caffine after 3:30 I won't be able to sleep.
But it could be a placebo...
