"i&#039;ve had severe insomnia for over three years and it was not uncommon for me not to sleep for two or three days in a row.  after trying several other prescription medications, none of which worked, my doctor placed me on seroquel.  i slept well but the side-effects were awful.  it gave me severe headaches and made me feel like a total zombie the next day.  however after the first week or so i decided to take one-half the amount prescribed and i still got the sleep but the side-effects disappeared. after three years of bad insonmia, i don&#039;t know what i&#039;d do without it.."
