Rolfing? If that has to do ejecting the contents of one's stomach in a response to too much alcohol then yes, I have seen the manuver performed on many occasions.
But really, I have no clue what rolfing is. Maybe you'd post some info on that...
It was all the rage 5-10 years ago in the PT world. It is a series (you MUST GO TO ALL THE APPOINTMENTS)of soft tissue treatments aimed at re-aligning the spine and extremities. It is hard core and one must be a "certified rolfer" to perform it.
