^^ Your chart is wrong, sorry buddy. I just replied to you in another thread where you listed this chart which you just made up yourself.
Clonazepam is absolutely NOT 2x more potent than alprazolam. They are equipotent, meaning 1 mg clonaz = 1 mg alpraz (which both equal 10 mg diazepam). In fact, alprazolam is very very (and I mean very, very) slightly more potent - though the difference is negligable. That is by weight (mg for mg).
As far as power and strength, you are wrong again. Clonazepam is NOT AT ALL "much stronger" than alprazolam. Alprazolam is a more powerful sedative at equal doses, while clonazepam is a slightly stronger anxiolytic at equal doses. They are more or less, equal. Of all the anxiolytic benzos, these two are likely the strongest anxiolytics (though bromazepam can give both a run for their money, despite it being less potent by weight - remember though, potency means nothing, its the strength of the actual drug).
The hypnotics (triazolam, nitrazepam, flunitrazepam, temazepam, midazolam, flurazepam, flutoprazepam, nimetazepam, and brotizolam) are all more powerful than alpraz, clonaz, and all other anxiolytic benzos - be it for sedation, anxiety relief, anticonvulsive action, etc. These are the "Corleone family" within the families of benzos.
Um, yeah, that chart was way off lol.
30mg Temazepam ~ 1mg Xanax
1mg Clonazepam ~ 1mg Xanax
22.5mg (roughly) Flurazepam ~ 1mg Xanax
7.5-15mg Midazolam (oral, not IV) ~ 1mg Xanax
3mg (roughly) Lorazepam ~ 1mg Xanax
15-20mg Diazepam ~ 1mg Xanax
All above are JUST IN MY OWN EXPERIENCE. Not an official chart, not taken from another site, so please NOBODY rely on my own little chart. Just listing how each drug compared in my own experience to each other in terms of potency. And demonstrating that it's stupid to just use you're own experience when giving out info that is presented as factual. Someone could die!
ETA: Well, for generalized anxiety Clonzepam is best in terms of not being as dependence-causing, and for its long half-life. It's quite potent, but not as relaxing as other benzos, and definitely doesn't give you any kind of "rush" like Alprazolam (due to it's quick peak plasma and short half-life) or Diazepam (due to it's rapid absorption by fat cells, where it is stored - Valium is highly lipophilic).
Alprazolam is useful mostly for a different type of anxiety: panic attacks and acute anxiety situations, like if you're giving a presentation and you know you get crippling panic attacks you could take 0.5mg before the speech. It is also useful for insomnia if you tend to wake up in the middle of the night and have trouble going back to sleep - it's short half-life makes it a good back up to have on hand if it makes you sleepy, and you know you won't oversleep like you might with say, Temazepam 30mg.
Diazepam is my personal favorite, but it's incredibly long-acting, has a ton of active metabolites (which then further have their own active metabolites, etc). It's the best muscle relaxer of all the benzos (in my personal experience from the above ones I've tried). It isn't great for panic attacks because it's pretty weak (20mg at once makes me drowsy - usually not enough to fall asleep but I've got super severe insomnia so that is just a personal genetic quirk I suppose).
For generalized anxiety, something like Clonazepam is safer. Diazepam has been shown to have serious and significant cognitive side-effects in clinical studies (to be fair - the study was of addicts who used Diazepam typically to either come down off meth or coke, or in combination with opiates. Also, their typical doses were quite high and would never be prescribed by a halfway competent physician).
I'm lucky enough to get all three (Xanax, Klonopin, Valium) prescribed (by one doctor, even!). But, I do have severe issues. Severe Panic Disorder, severe Agoraphobia, ADHD, Major Depression, Severe Social Anxiety (I think you guys get the idea that my anxiety is severe by now, lol). And bad insomnia as I stated earlier.
Thus, I get Xanax for acute panic attacks; Klonopin for general anxiety/panic attack prevention, and Valium as a muscle relaxer for a severe back injury.
I don't get euphoria with any benzo, just anxiety relief. I don't get why people would take these for fun...but I am a statistical aberration with my anxiety issues, so I suppose that's why I wouldn't get it. Closest it gets would be with Valium, even then, I can't fathom taking it just to "get high". There's smoking for that.
