Trazodone (it will make you sleepy but you will wake up feeling horrible, also, one day i took trazodone and couldnt swallow, it was horrible).

Amitriptyline (makes u a zombie next day also gave me anxiety)

Seroquel (maybe is not tooooo bad, but is the same as amitriptyline but less intense).

Levomepromazine (i dont see people talking about this drug here, is an antipsychotic, is very common to use here as a sleep aid, dont recommend)

Dramamine (believe me, i did thinking i would sleep, gave me horrible hallucinations)

Ambien (welllll... i love this drug for the comedown, i just dont recommend for first time users, u can end up doing shit).

Opioids (i never used any opioid but i see people talking about how effective it is, so...) (NOT PERSONAL EXPERIENCE)

Now what i recommend and most of the times works fine for me:

melatonin and some benzo after the end of your sesh (preferably one hour later), with a good hot shower (optional), and try to eat something (if you cant eat, try shakes like whey, i dont know, try to eat or hydrate a lot), ambien works for me like i said, but for some people it doenst, if you dont have anything in your home try some antihistaminic, benadryl i think is the name (sorry im not from us), if you dont want to use drugs the only key is WAIT, it will pass (if your coke is not cut with a lot of shit), a shower, try to relax, for me when im coming down nothing is interesting so i just lay down and wait to sleep, if i dont sleep, after three hours i start to feel better, not too depressed and shit, i eat something and get through the day sleepy as fuck, just remember that WILL PASS and dont forget to hydrate yourself, any other tips will help.
