"i take 3 ,25mg of quetiapine fumarate at night before bed for insomnia. it works very well. i sleep well on it without waking through the night. i have found out that i&#039;ve had to cut out citrus as it interferes with my meds stops them from working but apart from that its great. and i found when taking it i have to drink alot of water when taking them and have to eat something after them to help them kick in quicker."
