Answer 20

In my own personal opinion, increasing my body temp. makes me sleepy.

Answer 21

Found this explanation online

"As the brain creates adenosine it binds to adenosine receptors. That binding of adenosine causes drowsiness by slowing nerve cell activity. The adenosine binding also causes the brain's blood vessels to dilate, most likely to let in more oxygen during sleep. Caffeine looks just like adenosine to a nerve cell."

That makes sense. I'd go with a stimulant.
