Hi Diane,
I know I am not Ben, but I am also a person who has been through the IV Ketamine treatment. I went in inpatient for 8 days in May 2009. It is a constant IV drip, so it needs to be done in the hospital. If you have anymore questions, please don't hesitate to ask. You can contact me here or via e-mail. Feel better and take care!
Peace.
Michelle
