Sympathetic stimulation

Shit...how can i stop this sympathetic activation...heart pounding fast...muscles all tensed up...
The typical exam syndrome strikes again...
1st day insomnia, i thought it was caffeine effect so i cut it down the next day...
2nd day insomnia, i am pretty sure it has nothing to do with caffeine...
It's the spark of sympathetic stimulation...
Once it is on, it's hard stop it.
I know I am not alone. But it's difficult to control.
The way to overcome it is to meet my own demand, which I found it hard sometimes...
Created this Final Hurdle...so I can shout out my feelings...

OK.Let's get back to my study and see how.
Have 1/3 cup of coffee....
