Specifically hydrocodone taken with alcohol maybe not, but then again, I haven't looked for one, and neither have you. Hydrocodone is a semi synthetic opioid, it affects the mu opiate receptors, and causes effects more or less like other opiates/opioids. There are certainly differences in effect between all of them, some say oxycodone is "speedy" compared to other opiates, many say fentanyl lacks euphoria other opioids have, they're a little different, but generally speaking, they're going to produce the same spectrum of effects. It's not like comparing psilocybin to LSD, its more like comparing different weed strains. Maybe that isn't the best analogy, but i hope it makes sense. Hydrocodone isn't going to produce wildly different effects than other opiates, hydrocodones effects have been completely explored, and save for the research chemical opioids, so have all the other opiate/opioids. They're more or less completely understood, save for some R.C's or some of the stranger alkaloids in opium that have questionable and unstudied effects.
You're combining hydrocodone with alcohol. Its a pretty old combo. Opiate(x) + Booze = 3X the fun! Specifically mixing hydrocodone and alcohol is going to be pretty predictable, and its going to be pretty damn similar to mixing any other opiate with alcohol.
Alcohol produces improved mood, loss of inhibition, dopamine release, CNS depression, muscle relaxion, dulling of senses and physical pain, and a percieved "warmth" (which is blood vessel dialation) and more effects.
Opiates produce euphoria, improved mood, CNS depression, Loss of inhibition, muscle relaxion, dulling of senses and physical pain, feeling of contentment, feelings of "warmth, a pleasant drowsyness, and wayyyyy more.
BOTH alcohol and opiates are effective antidepressants, but only while they're used. The combination compounds the effects, as they share a lot of effects but they achieve those effects through very different pathways.
I Guarantee you could find a study (or many) done on the effects of opiates and alcohol being combined. You'll also find a lot of info that its actually pretty damn dangerous to mix opiates and alcohol. They're both CNS depressants, it compounds the risks of either one by itself, its all over bluelight, opiates + booze = dangerous. Opiates + benzos = dangerous. A shit ton of opiate O.D's happen because of mixing it with other CNS depressants, especially benzos.
Also, those hydrocodone tabs have a strong dose of acetaminophen, which really works your liver. Alcohol also really works your liver. Combining both at the same time REALLY REALLY works your liver, especially when taking more than just one pill. Both are hepatoxic compounds
Mixing alcohol with opiates isn't new, especially hydrocodone, it was the first pill i took, and the first opiate i mixed with alcohol. You should be able to find studies on alcohol and opiate combos pretty easily.
And the experimenting.......none of that's quantifiable, that's all anecdotal evidence, experiences.....which are useful, but you'll have no problems finding oodles of those online, here, on erowid, everywhere. And its not doing anything to further anyones understanding of hydrocodone or its combination with alcohol, any of their interactions or what they do in the body. To do an experiment you have to have a question, why you're doing it. whats your question? and it should be better than "what does hydrocodone do with alcohol?'
What it is is use justification. What you describe, music being awesome and blankets super comfy.......I would expect you to feel that way combining any opiate. Its not new and profound what you experienced, and you'd know that if you did some digging. I've heard your exact description of your experience from others doing very similar things. I'm just saying, if you want to keep experimenting and doing "research" you're going to need to take a much more organized, patient, and careful attitude. I was exactly you, and i did fine for awhile, but my tendency to do stuff without very thorough research and risk assessment fucked me and now I'm just an addict (once you are one you're one for life). Man, I had some big time scares and some very very shitty withdrawals and awful family episodes. And I know this all sound very patronizing and "smarter-than-you-look-at-me" but I was exactly you and it took a looooooong time of me being up my own ass before i realized I was just fucking dumb and reckless. So take this with a grain of salt and do your own research because im not smart but I am trying to warn you of the stuff that kicked me in the sack.
