I have been amazed by the Ketamine. So many doctors seem to be so scared of it, and the more experience and research I do with it makes me not understand why. Truthfully, I blame Nancy Reagan and her damn drug war, but I tend to blame her for a lot of things.Â
Ketamine can be psychologically addictive, but it is not physically addictive. I have taken ketamine at times daily for two weeks straight. When I stopped I was very surprised to find that the only withdrawal (if you can even call it that) was that I was little cranky for a day or two. Nothing a bong hit or two couldn't help. Another thing that is a amazing is it's short duration of action. Most times the amount I take does not inebriate me much and I can go about my day just fine--when I have had heavy hitters and I go for a higher dose it can be pretty intoxicating but it really only lasts about an hour. You don't get stupid like alcohol or opiates either--you are very aware of the intoxication and you don't want to do stupid things like drive a car or french kiss your cousin.
I will say this though, a heavy dose is just weird. I have done a lot of drugs and the only thing I could compare it to is a really strange nitrous oxide trip. As a "dissociative" it can "distance" you from things, I don't know how else to put it. Even when it does not work completely for me and I switch to the big guns like Imitrex, it still seems like a lifesaver. Sometimes it can take 20 min for a shot of trex to work for me--and anybody with clusters knows that 20 minutes is just to long. The Ketamine distances me and tones down the pain, making it a hell of a lot easier to wait it out.
So many Doctors are willing to prescribe narcotics that you build tolerance to rapidly for pain, cause physical addiction, constipate the hell out of you, lead to depression and withdrawal...the list of negative effects of the opiates is ridiculous (and yes, I still use them from time to time) For regular, non cluster pain, the combination of Ketamine and opiates seems to be a much better choice than just regular opiates--mostly because the pain relief is more complete and you can take less of the physically addictive opiates. When I was having some really painful teeth work done I was going for the hydrocodone and Cannabis mnixture (another great thing that can lower your needed intake of Opiates) and it worked all right but I was still in a good bit of pain. This seemed like it was eventually causing a cluster which I would take my Ketamine for--and the tooth pain would just disappear. I don't think the Ketamine alone would do it at the low doses I was using, but it seemed like the combo kicked ass.
Here is a link to "Postoperative Ketamine Can Reduce Morphine Consumption and Nausea"
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605142/
One study on Intraoperative ketamine showed that
"We have demonstrated that intraoperative preventative ketamine reduces opiate consumption in the acute postoperative
period by 37% in opiate-dependent patients with chronic pain
who are undergoing painful back surgery. In addition, it seems
to reduce pain intensity postoperatively in the PACU and at 6
weeks and to reduce consumption of morphine at the first postoperative visit. The findings of this study add considerably to the
body of literature pertaining to the efficacy of ketamine in preventative NMDA receptor antagonism."

To me, it sounds like if a Cluster patient has tried just about everything and ends up on Opiates, it would be a damn good idea to mix ketamine in there too.Â
Another thing about the Nitrous oxide--it is in the same class as Ketamine (NMDA receptor antagonists) so it's not that strange for them to have similarities. A big thing to be aware of though is that for me they seem to work synergistically. When I went to the dentist with a cluster I took a good 10 sprays then sat down and had them put the nitrous mask on--within a few minutes it was complete interdimensisional travel. Many of the specifics are a little fuzzy, but I could see all the dimensions of the verse (as I call it, because the Uni-verse would imply a singular space instead of the infinite unbounding cosmos that I was experiencing) splayed out like a deck of cards being shuffled. I could see into all the dimensions and I could see that my own dimension, the one where I was having a crown done in a dentist office was going downhill fast. I knew that if I didn't intervene, everything everywhere was going to dissolve into nothingness. Then I retreated to being a very small, shy child in the corner of a very dark room. Part of me was urging this child to DO SOMETHING! SAVE THE VERSE" and the little child would reply, "but I'm scared...I don't know if I can" Eventually convinced that every cosmos everywhere was about to be completely annihilated I slowly put the effort into raising my hand. It was like the air was complete thick tar, it might have been the most effort I ever put into anything. As it slowly got into the air I felt more and more exuberance---"I'm SAVING THE WORLD!"Â
About this time was when the dental hygenist looked in and found me sitting calmly with my hand in the air. She came in and asked me if I was ok--to which I gave no reply and stared at the wall as if I had no idea she was there. They promptly stopped the nitrous and I came back to earth, aware of the unbelievable beauty and strength of the world, the verse and myself. I was not aware until a few minutes later that I was in a dentist chair with a couple of worried hygenists looking in at me. Then I started laughing hilariously and asking them "what the hell just happened" To which they replied "I have no idea"
The rest of the appointment was kinda rough on me and the dentist, mostly because no one had any idea that I had saved everything everywhere (You're welcome folks, just another day's work ) and no one had any idea why I kept erupting into maniacal laughter.
So the lesson is--be real careful with the nitrous ketamine combo--unless of course, you're into that kinda thing. It was pretty cool.

BTW--thanks Doc, for all your input. Your presence on here could make a big difference for the folks that want to try this and are meeting resistance with their doctors.
