Oh my goodness, where do I begin with quetiapine! I was prescribed it when I was an IP on an ED ward due to insomnia and excessive exercise. Normally, i'd go to bed at 3am and wake up at 6am. But after taking quetiapine, I fell asleep at 6pm and slept all the way to 8am. I had to be wheel chaired down to snack in the evening because I couldnt wake up and walk down. I dont even remember having snack which for me is pretty impressive! It was really odd. I felt like a zombie for quite a while and I was taking it in the morning too, so I was knocked out for a while! But the effects do wear off after a bit.
Zopiclone had a simular effect with me. But it didnt last during the day, just knocked me out at night. But I find it makes me feel drunk and I halucinate. I will quite often sit watching my walls and bunches of flowers because they look like they're moving!!!
