I would have 2 suggestions.
One, make sure you are not on pain meds when undergoing ketamine treatments as they can interfere with the glia that you are trying to shut down.
Two, I would say that 2 hr infusions just might not be enough. Inpatient therapy would involve 5 straight days of ketamine and from my research that is where most people have success.

My daughter had many out patient without success. One inpatient with no success and then one inpatient with NO pain meds with total success.

Ask your doctor to consider talking to Schwartzman, Getson or Kirkpatrick for inpatient infusion rates.
