Thanks Paula and Suzi. I have heard some bad things about the Ketamine infusion and this is why during the trials people are often treated in hospital or have a responsible adult to supervise them in between visits. This did frighten me slightly but this has to be balanced against the number of people who have had no serious adverse effects and have reacted positively to the treatment when all other treatments appeared to have failed in the past.

I guess it's just a case of weighing up the pros and cons and making a calculated risk. All medication involves a certain amount of risk, let's face it.
