The best position for starting an enema is on your left side.
I am a long time enema user, and I am available to discuss all your options at (843) 455-9208. Call me at your earliest convenience.
Also, we are having Beach-e pHest, a health-care conference discussing enema use, in detail, in Myrtle Beach, SC, on October 8th through the 10th. Perhaps you should be in attendance. We will have at least two enema nurses, giving enemas to any attendees who need them, at no charge, other than the basic conference fee.
Please call or write me, at email@example.com, or use the phone number above.
