If you want a benzo that by itself feels like an opiate i'd say definatley try temazepam. I've only had the pleasure of trying it once in a 15mg dose and it was the nicest benzo buzz that i have ever had. I've also tried clonazepam, diazepam, lorazepam, alprazolam & oxazepam. I've had lots of experience with all benzos except oxazepam which only on occasion. I'm also going to *highly* recomand to you the drug clonidine, it's available as it's not sechedule 2. It's described or classified as an antihypertensive and i am prescribed it, in 0.1mg pills, 2 and a half a day, along with methadone 205mg and 1.5mg clonazepam which i have been on for over a year. You can immagine that by now i need to dose around 400-600mg methadone, 5-6mg clonazepam and weed to get a good buzz, and sometimes if i'm not that buzzed i up it up with a half or a pill of clonidine. But otherwise with a regular dose, i would usually feel good with it, though with a clonidine and 0.5mg-1mg clonazepam would make me nodd like fuck, though when i'd double or triple dose it was much more euphoric.
Anyways, i recomand the clonidine b/c it doesn't knock you out, and many of my opiate using friends like to use it recreationally. It will make you sedated, and close to nodding, NOTHING like a dirty gravol/dramamine high, nothing like a nauseating or dizzying shitty high. Instead it gives you a nice relaxing sensation of 'it's okay' feeling after 1 hour of taking 0.1mg pill and after 2 hours you feel incredibly comfortable sitting on your couch, like on opiates and you can nodd out like on opiates, though prob not as euphoirc, though it would come in EXTREMILY ESSENTIAL if you'd go to your pharmacy and get a tylenol 1 or aspirn 1 100 pill bottle with 8mg codeine per pill, and do a Cold Water Extraction (extremily, i repeat, extremily easy it's made of 2-3 steps) which would get you a solution without the tylenol or aspirin, only with codeine and caffeine in a 1:2 ratio, but if you got no tolerence to opiates which you sound like you don't, say 200mg-300mg of codeine (400mg-600mg caffeine) will only make you euphoric but will never make you nodd, or it will until the caffeine kicks in, but if you take that same amount with a 0.1mg pill or 1 and a half, the clonidine along with the codiene would DEF overpower the caffeine, thus allowing you to get a perfectly good opiate high the way it should be. I HIGHLY SUGGEST you do this, you can get 100 8mg codeine tablets from any pharmacy OTC in north america for less than $10 dollars, in my town for about $6-7. If you got no tolerence i guess it's worth it if you can't get anything else and are carving an opiate high badly, but if you got the clonidine it's especially worth it. With the clonidine it would essentially be like consuming codeine only, which for me was extremily euphoirc. I've used fentanyl, dilaudid, hydrocodone, oxycodone, demerol and codeine many times. The times that i've had pure 30mg codeine phosphate pills, a 320mg dose for me would be more euphoric and more enjoyable for me than 20mg or 30mg of oxycodone, with no tolerence. The reason is b/c if you've had pure codeine you know how sedating and warm and fuzzy the buzz is, is basicaly an euphoric morphine like buzz. Oxycontin is less sedating...just as fentanyl is..or hydromorphone, out of all oxycontin is the most though but all are extremily good and euphoric in their own ways.
Onto benzos, when i started using benzo i hated them. I first tried xanax and it made me so confused and dioriented without me realizing that i had a buzz and that i was high yet slurring my speech and stumbling, i fell into a deep sleep. After another try or two with xanax to try to like it the more i hated it, even with weed mixing a small dose of 0.5-1mg, it would completly ruin/overpower my weed high and make me zombified and slow, and when i'd stand up my motor skills were beyond fucked, almost making me nausious if i was standing up for too long at first. I tried lighter benzos like lorazepam which made me hallucinate everytime but not in 1mg-1.5mg doses, which were nice and lighter than xanax which is the crack of benzos. Valium 10mg made me feel nice the first time but as i upped it to 20mg after an hour it made me zombified and fucked motor skill wise just like xanax. I stopped using benzos until i was later scripted clonazepam. I liked this benzo at that time the most of all b/c it take 2hr to kick in and lasts 6hrs, but it's smooth and almost opiate like in that it's subtle and an accuaired taste, however i haven't met anyone who does opiates who didn't like clonazepam. Instead everyone i know who does opiates at first also hated or still hate xanax. Anyways clonazepam is smoother and the high isn't zombifing, it's chill and nice and calm, i think you'd really enjoy this one, but temazepam kicks in in 30min and lasts 3-4hrs, but it's high i think is more opiate since clonazepam is an anti anxiety and an anti spasmatic benzo and temazepam is an anti anxiety and a hypnotic, prob what gives that dream like light body feeling that opiates also give, nothing too strong however it felt like a nice codeine buzz with no tolerence.
P.S Just to let you know, benzos when you first try them esp strong ones like xanax or valium, arent especially pleasant if your idea of a perfect high is a opiate or weed like high. However, after a few tries with them in smaller doses, that you find don't fuck you up but only get you relaxed and mabye even a bit euphoric you start to loose the bad side effects such as the zombifing and loss of motor skills which go COMPLETLY away with a bit of time. In way, i can say as an opiate addict, that benzos are JUST like opiates in that they are an aquired taste. They are both strong highs, though with subtle euphoric effects which only with time you really get a taste for and look at. When i started opiates, i started with 5mg percs and i had a hard time getting high after going higher than 15mg at a time, 10mg would make me FUCKED and nodding but 15-25mg at once was a complete waste and it wasn't extended relase or nothing, i later learnt it was a histamine relase as well as a lot of competence in my body's cells (esp the liver which metabolizes every drug and chemical) which were filled by the tylenol, which ALSO caused heavy urine retention, again from much competence in the kidenys, two important oragans. Pure oxycontin which a year after trying percs i later came in contact with never produced such heavy urine retention (though all opiates do it though with opiates as well side effects complely fade away with use) or none of the liver damage that tylenol does. Also after using the 5mg percs for a while, i found a way that would work best for me, which was to take a 5mg pill wait for the buzz to go down, take another wait to go down, take another and so on from early at 9am in the morning till late at night all the time sitting on the couch watching tv (which still remains my favourite activity, and one of my big vices), after a while i would need 2 pills at once and so on. After 2 weeks or so of use, i found out i needed at least 3 pills to get a buzz and if i took 5 at once i could get a really good buzz. The same applies for benzos, even if you find it hard to believe it at first, i later came to love every benzo i could find. I would need at one point 5-6mg of xanax to start to feel a buzz, again it's the crack of benzos. Hope you find a benzo and take it slow with any benzo you choose, as you prob don't want an addiction. However as an occasional drug it's pretty safe...
