Drink about one and a half liters of lukewarm saline water (about 1% saline) as quickly as you can until you feel like vomiting it out. Churn the stomach by twisting exercises. Stand with feet apart at shoulder width and bend the trunk forward forming an angle of about 80 degrees to the body. Now with the help of the middle three fingers of the right hand, tickle the back of the throat to vomit out (vaman) all the water. Repeat the process of tickling the throat until no more water comes out which may mean that all water has been vomited . With continued practice one can stimulate the vomiting sensation and vomit out the water without using the fingers at the throat. Relax completely in savasana for about 15 to 20 minutes. Have a bland breakfast after about half an hour.
