2 mgs of Xanax + 3 Fioricet. On an empty stomach. Best high ever.
From a harm reduction standpoint, mixing barbiturates and Benzos is dangerous.
And while there a is cross-tolerance between barbiturates and benzodiazepines, and a regular user of either can get a pretty..uhh..entertaining high for other people to watch when taking the two, someone whos system is naive of both should avoid this combo. Some people do find the combo recreational. I do not.
I personally have never taken Fioricet as I have only been given I.V. phenobarb while also given a benzo (Midazolam) to try and knock me out after my insomnia had me up for 4 days straight (The sleep dep with lucid hallucinations was was fun tho, till my heart started tripping out).
I was extremely relaxed but absolutely hated the feeling. For me it was the feeling I used to get when I drank, then realized the last few shots were a mistake pushing me over the edge from fun times to uh oh this is gonna end up with the cops and paramedics. Only enjoyable part was watching the doctors go wtf, why isn't this dude snoring yet?
For whatever reason most sleep meds do not work on me. And no it wasn't due to any other substance, just my fucked up body chemistry. During that bout they end up having to give me Etomidate. Then I slept for 18 hours, went home from the hospital and slept another 12.
I also cannot blackout, while sounds like something that would be beneficial, and has been at times, it is not as cool as you would think. It makes things like colonoscopies and other procedures that use conscious sedation very unpleasant. Also doctor accused me of being on drugs since he had use double the amount of fentanyl and Midazolam with a anesthesiology nurse to actually knock me out completely for part of the procedure since I kept moving and squirming as he shoved the camera up my rear. And trust me its not the kind of rear view camera you want
