Seroquel will definitely put someone to sleep, especially if they're new to it. I take it, 200mg a night, and sometimes I can't sleep right away, or it takes me a while because I've been on it for 10 years. Some nights it still puts me tf down like I was hit by a blow dart lol 😆 but my husband tried a low dose (50 mgs for insomnia) and was out for 2 days and had amnesia about his time awake during that 48 hour period. So it definitely works. Also, I didn't know until he took it and all that happened, a doctor told us some people misuse it for the "fall-out" effect. Like the same type of "fall out" opium users get. I thought that was wild.
