Dunno personally but folks tell me yes HOWEVER DXM tends to knock most people right the fuck out, even me and I can go days without sleep without caffeine or drugs of any kind, so yeah benzos would make it even harder. If you do, tho, don't try to counter-act it with any uppers like crack, meth, E, etc. DXM takes 2-6 hours to peak but when it does it's like speeding HARD. Heart racing like mad, sweats and really cool tactile 'feel good' skin stuff. DXM kicks ass, but it also kicks your ass. Try not to fall asleep or else you'll just wake up feeling hung over AND BEWARE ROBO-ITCH! Try not to think about it and scratch, even tho it feels super-good to scratch Anti-hystamines help, but DO NOT take any more than an OTC dose, hystamines KILL Also DO NOT chug syrup that has ANYTHING AT ALL in it besides DXM Guafenesin, Acetometophen, and any anti-hystamines will KILL YOU long before you trip If this is your first time, have a sitter. Dissassociatives tend to be bad about causing The Fear DXM mixes well with pot, caffeine, and betel nuts Try to avoid alcohol because the toxic combo could cause liver damage
