In response to couple things recently said,
It is true that there is ONLY one pharmacy in the country that dispenses Xyrem. When you are prescribed xyrem, you don't receive a scrip. Your doctor/office contacts the pharmacy themselves, and the pharmacy then ships it to you. If the patient is just starting it, the pharmacy calls and makes sure you understand how to use it, etc.
The thought that a doctor has to have any contact with the DEA is bullshit. Xyrem is a Control III scheduled substance- hell, adderall, ritalin, and most CNS Stimulants are CII and doctors don't do a damn thing with the DEA. I would think it's assumed a doctor knows what he is doing, and wouldn't prescribe such a medicine unless it's necessary (under penalty of law and loss of license). These are approved drugs by the FDA for medical use.
When they are used in form of abuse or sale, however, they are then considered CI drugs (obviously, more severe).
The ONLY form Xyrem is dispensed as a clear liquid containing 500mg/mL. The patient dilutes that in 60mL of water. Two doses are set up at once, one taken at bedtime, and another 2 1/2 - 4 hours later. No powder is Xyrem, nor pill.
When talking about a narcoleptic's sleep, you can throw all order of stages and durations you know out the window. We certainly don't sleep like you, and not for the majority of reasons claimed here.
Narcoleptics exhibit more stage one and REM stage sleep, and not enough long-wave sleep. Also, while characteristic for the time period from sleep onset to REM to be roughly 90 minutes, narcoleptics can (and regularly) fall into REM cycles directly - 30 minutes from conciousness. I can pass out and wake up five or ten minutes later with detailed dreams.
A neurotransmitter called hypocretin/orexin helps to regulate your sleep/wake cycle (awake at day, asleep at night, not much intrusion into the other at inappropriate times). Narcoleptics have been found to have very little to none of these present. That's the best idea they have so far. Basically, you can think of our sleep/wake regulation as a light switch- it just flips back and forth regardless of anything else, and we then fall asleep / wake up at night, not be able to go back to sleep, etc. There isn't much of a buffer zone.
So long as xyrem is taken as prescribed, in the prescribed doses, tolerance and addiction are extremely rare. If an addiction were to occur, be it with xyrem or other ghb, withdrawal symptoms would not be present more than a day or possibly two. GHB is not toxic whatsoever, and the majority is metabolized into CO2 and H20 within a couple hours. Half life is 1/2 hour to an hour.
It sure as hell doesn't cause neuro endocrine damage, and it's effects on sex are nothing but positive. It's thought of as another beneficial feature without any drawback by health professionals. Without getting into it, it ironically is particularly helpful to narcoleptics with cataplexy.
You're insane thinking amphetamines are less of a risk than ghb. following prescribed doses of CNS stimulants, cardiovascular strain and damage is done, and having a much longer half life, detrimental effects stay longer.
