i never abused benzos but i took seroquel in the hospital and it made me feel really light and fluffy and really sleepy, i felt like i was dying when i was passing out although it felt very peaceful. It made me want to sleep for the next 3 days straight after the night though. My friend who used to abuse random benzos and depressants regularly seemed very drowsy and just not there mentally and didn't remember a lot of stuff while he was high due to the extent of his abuse.
