Well supposedly clonazepam=alprazolam mg for mg, but in my opinion knowing how each of these works, I find klonopin to be a lot different than alprazolam, even if they are equipotent. I feel like klonopin is kind of like xanax, but lasts longer, and doesn't have as much of a punch when it hits you, its kind of like a longer lasting more subtle version of Xanax. I like it a lot more than Xanax personally, and valium is my favorite benzo out of them all, used to take that instead of klonopin and would still take it if I was prescribed it! But that's just me I'm prescribed a fairly good sized dose of klonopin a day 3mg plus a few extras in case I need them, right now, because I have terrible social and general anxiety, with the very occasional panic attack. It works really good for stimulant comedowns to me, I chew it or parachute it to get a more fast onset, because when you swallow clonazepam whole, it takes like 30min to an hour to really start to work then just sneaks up on you. Plus klonopin tastes like candy to me! no nasty bitter taste at all like Xanax has, its sweet and minty almost.. if you take 20mg of valium and 0.5mg of Xanax, I would try maybe 0.5mg of klonopin instead of the Xanax to start, then if that doesn't work another 0.5mg.. but remember it does take a min to kick in compared to Xanax's almost immediate onset, if you chew/parachute it it will kick in fully like 10-15mins usually and just get stronger til it peaks, it lasts like 4 times longer than Xanax for me too.
The first time I took klonopin I had only tried Xanax prior to taking it, and I could handle like 3-4mg of Xanax usually, but I underestimated the strength of the klonopin being relatively new to benzos besides xanax and my friend gave me like 5 1mg tabs I believe. I swallowed 2 of them whole, and because it didn't kick in super fast like Xanax I chewed another and kept going til I ate all 5 in an hour or 2, I was just completely faded... cant really rememeber what happened that night, all I know is I almost blacked out by stupidly taking way too many kpins too fast, and underestimating their strength. So tread lightly with them if you do get some. Especially mixing strong uppers like mephedrone and strong downers like benzos, it definitely helps that you aren't completely naïve to benzos though. Just be careful!
