     but man take those all the time and you will be pretty 
     damn irritable and mentally tired after awhile.

No argument there.

     It's natural for "ADHD" people to work in waves. Long 
     sprints and rest in between. I know it's popular to 
     advocate drugging yourself, but people reach for that too quickly.

This is easy to say, but there are a variety of reasons why not everybody (and in fact, most people) can't precisely tailor their lives to meet the whims of the ADHD brain. Even entrepreneurship has lots of "boring" stuff that you have to simply plow through to get to the interesting stuff.
