insomnia
"I have gave quitiapine 5 stars as it definitely allows me to sleep right through the night. But I have been on it for 15 years and still experience dreadful side effects. I have reduced from taking 800mg in the morning to 300mg in the morning yet in the evening and the morning I can barely function and am tired and groggy all day. I have tried to take it earlier and earlier in the evening in the hope of having less side effects in the morning but nothing works. Plus it gives me the appetite of a racehorse. I also have nasty withdrawal symptoms whenever I try to taper off completely. For me this drug is a necessary evil and I really wish I didn't have to take it."
