Need To Sleep While On Meth?

i just did meth for the first time...yeah i was regretting it 20 minutes after i smoked it because i was already craving more. ive had like 50 hits of meth in like last 30 hours and i need to sleep..i can still tell im pretty speedy but i started to come down and it was horrrrrrible feeling so i've still been smoking it just so i haven't had to come down. it'd be great to know what i can buy from a like convenient store that would put me to sleep. i know nyquil would do it but im not sure how nyquil affects reacts with that of meth..(couldn't find no information on those 2 drugs together) websites pretty much said the best ways were like benzo's and klonopin. mostly benzo's. i also can't get ahold of alcohol atm, also im a lightweight so id probably get a hell hangover from 2 shots of jack. if any 1 has any information of taking nyquil while on meth..please tell that's 1 of the very few options open to me. i don't exactly feel bad, but i know im sleep deprived and i can imagine how much better id feel if i slept..cus been up 2-3 days. oh and last but not least, i wouldn't do this drug again if someone payed me 200 bucks for it. lol that's how much i wanna stay away from it after this experience. er pls answer fast cus...i'm just anxious to know i also wanna get sleep asap b4 i start to come down
