Orphenadrine sounds amazing. Can it be IV'd? You must be in Canada? Apologies if not. They are otc there am I right?
Is it much different from diphenhydramine?
Yes it can be. I'm in the USA actually. I'm not to familiar with what's available OTC or by prescription in Canada. No need to apologize though! As honestly I'd be better off in Canada from what I've heard. At least from the Canadians I've spoken to.
Actually most anti-histamines are not over the counter in the USA. Orphenadrine, Hydroxazine, Promethazine, Etc. all are controlled in the US. Diphenhydramine & doxylamine are OTC though. I find there to be differences between the "generations" of anti-histamines. As to if it can be IV'd; I'd say yes. Again the caveat with any of this being that one uses proper micron filtration. I've tried all 3 of the ones I mentioned both ways; orally & IV as I was fortunate enough to encounter them on regular basis at one point. Orphenadrine is to my knowledge considered the "best" of them. I found them & Orphenadrine in particular to be more euphoria enhancing than say diphenhydramine. As opposed to diphenhydramine which I would opine subjectively potentiates the sedating aspects less so than the euphoric aspects. Again it can vary & is very subjective.
Obviously they all reduce histamine which changes the rush with some opioids. For exampe Morphine is a totally different experience with much less histamine release IMHO. Some people hate IV morphine specifically due to the large histamine release. Now a days with anything other than fentanyl analogues being unavailable where I'm located it hasn't played a role in quite some time. It's been years since I ran into real H. Other than going the dark web route which has it's own set of quirks & issues involved I don't expect to see it available again any time soon in my general area sadly enough.
Something else I'm jealous of is soma? Is this still available in the US or Canada?
Soma (carisoprodol) is available as a prescription drug in the US. It used to be unscheduled. It's been a Schedule IV controlled substance since 2012. Depending on what part of the country you live the availability varies. If you're in the SW near Mexico it's widely available. I used to get tons of em when I lived in the SW of the US. I also had scripts for them for many years before the whole "Opioid Epidemic" utter nonsense started. They are quite pleasant. They are about the only so called "muscle relaxer" than I've tried that I actually find enjoyable. Rather than just sedating. Don't get me wrong they are sedating but compared to say tizanidine or cyclobenzaprine for example; Soma is a much more pleasant & recreational substance. I have many health issues personally & I found Soma to be the only "muscle relaxer" that actually did so. It's worth trying if you get the chance.
I always combined it though which is not recommended unless you're experienced with doing so as it can be an exponential multiplier in terms of systemic depression. As people tend to forget benzo + opioid + soma is not equal to 1+1+1=3 it's much higher. The response is not a linear curve. In my case I'm a chronic pain patient & at the time was prescribed the Soma along with Klonopin (clonazepam) at times Restoril (

temazepam

) & various opioids. I also have been on medications in these classes for at least a decade. As such my tolerance is quite high.
No one should take my anecdotes about my experiences as a statement of safety. Depending on the time period of my life; what gets/got me through the day('s) at times would have killed an elephant. Thus I'm including this & my prior statements just now as my obligatory disclaimer for any one else reading this.
Soma is not as widely available as it used to be in the US. I'm not really sure the availability beyond that it's less TBH. I know it's not widely available in my area. I believe it's still available elsewhere just not as much? I'm guessing it's still widely available in the SW as there most peoples supplies came from Mexico. As opposed to prescriptions.I could be wrong on the availability though; I'm not positivte.
What's it like compared to benzos or ghb?
I've wanted to order some. To try for years
I find GHB to be it's own beast. I'm quite familiar with that substance. It's not "widely" available. in the US to my knowledge. I've been lucky in that regard. It was available in the SW through people I knew that could acquire essentially anything. Long story there. Most of my experience with it though is through Xyrem brand prescription Sodium Oxybate. So 99.9% of my experience was with pharmaceutical grade material. It's an interesting substance but besides my rambling there I honestly couldn't compare it to benzos or Soma. I find GHB to be a unique experience that I couldn't easily compare to any other.
I'm very familiar with benzos as well. Soma is most similar in effect to Restoril (temazepam) from my experience. In terms of pharmacology IIRC a portion metabolizes to Miltown (meprobamate). However; to my knowledge contrary to popular belief carisoprodol itself is responsible for a majority of the drugs effects as opposed to it's metabolite meprobomate. Don't take this as gospel as I'm going off the top of my head but IIRC.
So to sum it up I'd say Soma is most similar to Restoril (temazepam) in terms of effects from what I've experienced. As temazepam is a potent muscle relaxer I find it most similar & in my opinion enjoyable. More commonly people might be familiar with Valium (diazepam) a portion of which metabolizes to temazepam. Though I'll let it go before we get more into pharmacology of various prescription (in my country) or RC benzodiazepines.
I myself have only ever ordered a few RC's at one point. Some phenazepam when I needed to substitute for my clonazepam when I had prescription error at one point is what I recall most. I haven't really messed with ordering anything else RC wise & though I've explored the darknet markets a bit I've never actually placed an order or even acquired the crypto to do so. Regardless; can't discuss sourcing. I just realized I'm just rambling as usual.
Just think I got interrupted & went to the store in the middle of this post. I was going to apologize for not having the time to properly answer. Apparently even when I'm interrupted & end up trying to keep it short I still am so effusive I pretty much write a book.

My apologies for the length & enjoy your Sunday.
