My physician recently told me that if I didn't cut back on the caffeine intake and junk food that i'd be looking at a 'stage 2 bubble,' myself.

LET YOURSELF TAKE NAPS, decaffeinate and learn your REM cycles and try and wake up in the sweet spot of feeling rested.How this works in a functional way, if I know I'm going to be working for 48-100 hours straight, I will not use caffeine at all, taking naps at 10am, noon, 5pm.... whenever.

They have dozens of offerings at any time and each deal has a PPM you can read (make sure to drink caffeine before hand, they are boring).    

I think it has little to do with my caffeine intake and everything to do with my eagerness to start the day, crush the day and to be successful.. 

On March 4, 2015, I came to work with a very heavy heart (partly because of caffeine overdose).

I also make sure I give plenty of drinks with caffeine to give them the boost through out the day that helps :) !

Had too much caffeine this morning.

My secret is drinking tons of water, drink tons of caffeine, cook your own food, and get at least 6-7hrs of sleep. 

I think his body produces natural caffeine.

Sure, there are days when it takes a few Red Bulls and caffeine pills to pump you up and reinvigorate the acid in your veins.. but the end result is worth it every time.
