<p>from my experience of 6 months of daily caffiene use last year. </p>
<p>regular coffee: works. but takes at least 1-2 hours before you get a rush.
green tea: works. but also takes 1-2 hours.
pekot tea (indian): works. but less effective than green
starbucks expressos: same as regular coffee. not that much difference.
redbull: TERRIBLE compared to coffee to keep you awake.
monster: A bit better than redbull, since each can is twice as big
bawls: meh, don't bad
caffiene pills: good stuff. but CAUTION: ONLY TAKE ONCE IN A WHILE (LIKE AT MOST ONCE A WEEK). a friend of mine who used to take 3 pills a day in the morning went insane and got amnesia. Not kidding.</p>
