my 0,02 will be - do not overdose caffein before public speaking. one can of coke is enough before 30 mins speech.

if you have more you will rush your speech to much, you will sweat and fill strange because of heart rate

I agree with you. I usually try to avoid coffee (or at least limit myself to decaf) which seems to help a lot. Unfortunatley, the downside is I usually get a headache which probably says a lot about my addition to caffeine.
