I think the warning should be "If you're not a doctor, don't play at one".

Not everyone can afford a good doctor, so experimenting on their own might be the only way to fix something. People have been hacking their CPAP machines for awhile even though it could kill them.

I can afford good doctors. They are 90% waste of time. 10% life saving.

Good Support groups are far better for your health. Although it often boils down to cut carbs.
