Yes ketamine is prescribed for depression, I have received 3 ketamine infusions (in Texas) for depression and it helped enourmously. 80 mg IM 3 times with 3 days inbetween each session. Great high, I just laid on the couch in my doc's office and listened to some happy music. In fact, I spoke on the phone with a Dr. Nancy Sajben who lives in California who for a absurd $400 an hour and a 3 hour initial appointment will prescribe ketamine nasal sprays that you take about twice a day.
Do you have any articles that pertain to the use of DXM as an anti-depressant? How long does it take to work? Also, seeing as it's a CNS depressant, I'm curios as to how that would even help.
Actually Desoxyn is prescribed for Obesity and ADHD (
http://www.webmd.com/drugs/drug-9124-Desoxyn+Oral.aspx?drugid=9124&drugname=Desoxyn+Oral#uses) under the tab 'Uses' on that page is says so. In fact for Narcolepsy your more likely to be prescribed GHB (Xyrem).
And honestly this Desoxyn is pretty crappy in the sense that it does not work nearly as well for me as ampethamine salts (Adderall). I even got the brand name to ensure that is was pure dextro-methamphetamine. I took 5mg and nothing really, could eat and sleep not really focused on it at all. Also, you could take desoxyn for life at a therapeutic dose (5mg - 25mg orally) and probably be fine. The negative propaganda about the recreational use of methaphetamine has soured it's perception as a useful medicine. People who use it recreationally are taking about 5 - 10 times a maximum therapeutic dose inhaled all at once (125 - 250 mg). Not only that, they don't sleep for 72 hours+ which after 72 hours of no sleep your bodies organs start taking a permanent hit to their health.
Honestly, a microdose of 15 micrograms of LSD everyday would be my prescription of choice.
