I seem to have similar issues and personality as you. I co-founded a startup last year and started at a frenetic pace, but was unable to turn myself off.

Over the last 3-4 months, the insane productivity was replaced by constant anxiety which mutated to burnout, and forced me to take a break from the company because I basically stopped functioning.

At this point, it seems the choices are either figure out how to set boundaries with myself and work at a sustainable pace, or just avoid these kinds of positions (founder is probably the most extreme type) and the addiction to work that they tempt.
