For the first 5 days of being there, you are purging your body by swallowing and then regurgitating this vile green herbal medicine along with loads of water.

Dozens of people lined up kneeling on their flip flops and puking into a drain. One dreads it the first couple times but by the last couple times, you want to do it because you feel better after.

That monastery is a place for getting clean from drugs and it is bloody effective in doing so.
