This drug has huge potential benefits for treatment of severe depression, FM, CFS, PTSD, and probably numerous other chronic neuroimmune illnesses. I have read all the literature too. Waverunner, you are right to be excited. This would probably work extremely well for you. It is a potential boon for many of us.
But it will never see the light of day because it cannot be patented so nobody has any interest in spending big money on long and expensive trials. And as has already been warned: don't take it !! Wait for years and years of official testing for some official body to declare it safe and effective. Or wait for some kind of "guidance" on dosing, when like most drugs, dosing is almost always highly individual and specific. In other words, most of us will be dead, or too old to care, before it is ever approved.
The kiss of death is that it is used recreationally, mostly by folks in Europe, so by definition the US drug nannies will declare it as having "no medicinal value." Such is the stigma of the Nancy Reagan "just say no" drug wars left over from the 1980s.
Never mind that Ketamine, not to mention Ecstasy, and medical marijuana have all been found to be effective in treating PTSD in returning Iraq and Afghanistan veterans. To hell with them, the self-appointed morality police of the drug world will decide what you get and don't get. Load up the vets with SSRIs, whose only side effects are suicide and rage fits, plus other new exotic off-label junk that nobody knows the true long term effects of.
If you are a CFS patient, living in pain and disability day to day, and you have access, legal or otherwise, to drugs such as Ketamine, Ecstasy, or medical marijuana, I highly encourage you to use your own judgement and to experiment if you think it will help you. There are literally millions of people who have used these substances, including our *past four Presidents*, and any potential harm from them will always be highly, highly overstated. Our most hideously destructive drug is alcohol. Not Ketamine, Ecstasy, etc.
I can assure you, the crazy anti-psychotic, anti-seizure off-label junk (Seroquel, Neurontin, Abilify, etc) being peddled, really aggressively, in doctors offices is no worse than the side effects of these drugs. These so-called "safe drugs" generate massive profits for pharma companies. The companies themselves have no idea what the long-term side effects of these are. But they will decide what is "safe and effective" for you and what is not. CFS patients, save yourselves, because this is an example where, again, nobody really cares about you.
