A friend of mine used to (and maybe still does) get prescriptions for quetiapine (i.e., Seroquel) for a "mood disorder". She never would take it, but only satisfy her doctor by accepting the 'script and filling it. She had a shoebox of at least a year's supply of the stuff. After imploring her to let me have them for insomnia, she finally acquiesced and handed me a bottle.
The first experience was uncomfortable and caused dysphoria, dyspnea, tachycardia, anxiety, xerostomia, slurred speech, violent behavior, asthenia, dysphagia, erectile dysfunction, syncope, nasal congestion, vertigo, lethargy, cognitive impairment, and a feeling as though the force of gravity had increased on my body. I did get some sleep, however. So, I was thinking the unappealing effects of the first experience were coincidental or just a one time thing that would go away after further use.
After trying the drug 5 more times, I concluded that these effects were not coincidental, but that they were unavoidable and inherent side effects of the drug itself. I haven't used it since, and don't plan to, either.
I observed most of these same side-effects from Trazadone and Lexapro, too.
I had actually been prescribed Lexapro for depression (which was really social anxiety misidentified) at 12 years old, and had been physically addicted to it from 12 to 15. I was fed up with the erectile impotence, weight gain, fear of missing a dose (which, if missed, I'd suffer with diarrhea, severe abdominal pain, vomiting, and intense headache all day), depression, anhedonia, and worsening anxiety—the very disorder it was supposed to improve.
And so, I quit cold turkey. It was absolute hell. If hell is filled with puke, watery ordure, and stomach cramps of an unbelievable intensity, then this was indeed hell. And it lasted about two weeks. But afterwards, I felt as if a fetter had been removed; I felt emancipated from this vile, insidious substance. Most importantly, though, I gradually began to feel like me again.
If I were you, OP, I wouldn't waste my time and effort spending weeks or even months trying to ween myself off this wretched stuff. I would grow some balls, quit all at once, and wrap the whole thing up in a fortnight. You'll want to die initially, but it will all seem worth it in retrospect.
