Kim,
Yes, it is like pcp. But if you think about it, look at the vicodin, percocet all that medication. The advantage to ketamine is that it doesnt lower your blood pressure at all. here is a link to a video about ketamine infusions that i think will answer alot of your questions.

If you can get infusions with a knowledgeable doctor there is nothing to be afraid of. They give clonadine to stop that. And also for a few days after my infusion i take klonopin or clonazepam and that helps with any side effects after that possibly can happen.
I look at it this way... who cares if we have bad side effects for one day. How many days have we taken medication that made us feel like poop that did NOTHING? here is an opportunity for a medication that does wonders in our world scoop up the chance while you can. tell ur doc u want the meds that we have with our ketamine to knock the side effects and you are good to go
my dear love ketamine
