Quatiapine, as with most neuroleptics is about as addictive as big hairy dangling donkey balls. Physically, not a chance, but the calming and sedating effects experienced whilst under its influence may cause a slight, note a very, very slight psychological want or desire to take the chemical for the aforementioned results when either a compromising situation is being faced or where an anxiolyse state of mind is required, for example when the need arises for a fast chemically induced shortcut to fall asleep. I've only ever used it as THE VERY LAST RESORT for coming down from stimulants. It's unnatural way of antagonising Dopamine, Serotonin, Epinephrine, Norepinephrine, Adrenaline and more than 28 other neurotransmitters within the pre-synaptic cleft causes an array of negative side effects which can be as mild as a sudden drop in your general mood, drop in core body temperature, high blood pressure and slight symptoms akin to Tarketive Akhasia with muscle twitching and manual breathing all the way to full-blown panic attacks with irregular heart murmur rhythms where you can actually see your entire abdomen shake with every beat to the most extreme and unpleasant paradoxical effects such as insomnia, auditory and visual hallucinations, even to the extent of actual delirium. I've used it hundreds of times to either just fall asleep or as a quick come-down from stimulant binges but until one random night of taking it I will never use it again. I've never ever in my life experienced a panic attack until I used 300mg of Quatiapine to come off a 3-day Methcathinone binge. Thought I would be asleep within an hour as usual but not this night, I started having the worst mental feelings of old regrets and every shit incident in my life played in my head over and over and I felt more and more uncomfortable, physically and mentally with each passing minute until I could actually feel my stomach turn into a knot, I physically shot straight up in bed clenching my abdomen with a heavy feeling a dread coming over me in waves that I have never felt before ever and also a continuous anxious state of total panic arose to the extent that I actually though I was experiencing physical bodily death. I don't know how I made it through that mentally but after hours of pacing back and forth in an entirely dark en quite room and on the verge of going to the E.R. I somehow fell asleep after what must surely have been 4 hours of this horrendous experience. Even my worst bad psychedelic experience fails in comparison to this chemical substance.
