Dr. Charlie Han's chair that seats you on your head.
 

And ligation/ banding.

Inquiring minds want to know how long until you feel well afterward?

like inverting?

Yes. I am attempting to gain information on an...um...delicate matter without coming out and using the words.

best way to know how you would feel without barf...take a low ottamon or bench or a yoga ball would work better...and back bend your head to the ground...you will feel very dizzy at first it take great practice...to invert for any length of time...in yoga i can stay in pose for about 15 minutes

The examination chair in Dr. Han's office is knelt on and then you find yourself upside down, or nearly upside down.

Quite an experience.

No one told me what to expect.
