Hey, /sci/entists.

I am somewhat of a caffeine-junkie. Being so, I believe I have built up some resistance to the chemical. Tonight I want to pull an allnighter, but I don't know exactly how much caffeine is needed to keep me awake.

I know that 300mg is enough to get me all jittery and hyper, but that is pretty much the extent of my knowledge.

Does the quantity neccessary to keep me awake vary by weight and body type, or perhaps age?

I also know the biological half-life of caffeine, approximately 4.9 hours.

Will you help me do research so I can perfect my dose intake? I'd be extremely grateful if you did.
