In all the clinical literature I've ever read, everybody who attempted suicide with a singular 50,000 to 100,000 mg megadose of fluoxetine didn't die or suffer serotonin syndrome (which seems to required a sustained exposure to increasing doses of SSRI medications), but actually got BETTER!
One girl with a severe case of OCD tried to kill herself by taking around 50,000 mg fluoxetine, then all signs of her OCD completely disappeared for six months. (Wellbutrin is FAR more dangerous. 450 mg buproprion can cause seizures which can easily kill.)
Because of how desperate my situation has become, I will be providing my psychiatrist with all the clinical literature on the benefits experienced with all the various cases of fluoxetine overdoses I have researched at my local graduate college, and express my willingness to voluntarily attempt a singular megadose of fluoxetine under careful medical supervision at the teaching hospital where he has admission privileges, since I'm out of other treatment options for getting better, and there is significant clinical literature supporting the efficacy of singular mega dosages of fluoxetine for instantly getting better for extended periods of time in emergency situations. (A teaching hospital is supposed to be a research facility, and I'm more than willing to sign off on the risk or trying a megadose of fluoxetine while hospitalized to attempt getting better. Maybe all of us there can learn something that will help improve the human condition.)
Can I obtain a medical green light for such an experiment? It way be possible, since I'm long overqualified for psychiatrist administered euthanasia wherever that modality is practiced, and I'm winning to attempt it under voluntary hospital supervision. If the mental health profession is legitimately serious about seeking ways to prevent suicide, this seemingly radical idea is one I expect they'd be on board with.
