>>I'm surprised that you're commenting about the caffeine and not the modafinil!

I know nothing about modafinil.

>>Caffeine has lots of wonderful effects on the mind and the body

It allows you to be productive even after not enough sleep. Unfortunately you can only keep this up for so long. In my case I now only use caffeine when I really need it. I'll gulp down three or four cups of coffee if I need to do all nighters. And because I have virtually no tolerance to it anymore the caffeine will work like a charm and I will not feel tired at all.
