There was a report released recently about how small doses of caffeine are best to stay awake
. and
that Gourmet coffees are Caffeine bombs, containing up to 400mg of Caffeine in a single 20oz cup (20 oz is the venti hot size at Starbucks -- the venti cold drinks apparently hold 24oz).
I find that the problem with me is not in being able to stay awake -- I can usually stay awake without the aid of caffeinated beverages, but rather the problem of making effective use of time.
I agree with you. There's no need to rely on caffeinated beverages if you make effective use of your time and try not to take on more tasks than you can handle. In the long run, caffeine is still not healthy for a person even if they come in small doses. =)
