In reply to Caffiene helps?, posted by HMK on March 20, 2002, at 8:12:00
Yes, caffeine does help considerably for many people, but not all. It's a stimulant & in those who aren't anxious, it will brighten mood & alertness for a while. It allows for clearer flow of thought, relieves fatigue, increases motor activity. Trouble is, it's not only a CNS stimulant but affects a lot of other body systems.
It also decreases cerebral blood flow (NOT NECESSARILY A BAD THING) which is why it's so effective in reducing headaches by constricting blood vessels.
A little is good, much more can have mixed effects as different body systems are effected.
