Probably 90% of all colonics take about 1 hour. It could also be shorter or longer than that, based upon the judgment of the hydrotherapist and you. For your first visit you may have to come 20 minutes early to fill out your Health History Intake form on one of our computers. Of you may fill it out online before coming in. On a first colonic you should expect to spend an hour and a half at the Temple if you fill out paperwork there.
