"i&#039;m a 26 year old white male. i have been taking seroquel for sleep for about a year now, my doctor prescribed me 400mg quick release to start, the first time i took it, within an hour, i felt like i was having a heart attack, my heart beat sped up an incredible amount and i was terrified. later had the dose lowered to 200 mg and the heart rate issue was much less but still there, i have been taking the 200mg dose for about a year now. it helps me fall asleep within an hour of taking it and i get pretty decent sleep, not sure how deep it is but i sleep. i&#039;ve read about how prolonged usage of seroquel is like a chemical lobotomy, i hope this is not true. i am a creative type and i have a lower creativity level ever since i started taking it."
