my experience with the ketamine is different... i'm up to 3 cc's and i take it every two hours as needed. sometimes i feel as if i'm drunk, depending on if i first take it in the morning, or if i haven't had any during the day. but as it builds up in my body over the day the results last longer, the pain might not go away but its definately lessend. i won't drive while on but if i take it continuously at night then when i wake up i don't have such intense pains.
