I know Clonaz inside and out, better than most doctors. Be warned, extremely easy to become dependant on Clonazepam and the withdrawals are literally the equivalent to torture. This is not a joke or an exaggeration. Taking it once a week is pushing it. Taking it twice a week is pushing it more. Taking it 3 times a week is guaranteed physical addiction.
Anyone who tells you otherwise here or anywhere else has no idea what they're talking about. I have taken this drug off and on for most of my life. I've quit cold turkey twice off of very high doses, and I've also quit using the much safer, severely slow tapering method (taking longer than a year).
This drug is in NO way a joke, and should never be taken recreationally.
I would say the only reason to take clonazepam is if you're having an anxiety emergecy.
If you've never taken it before ever in your life, you can get away with taking it for a few days (LESS THAN A WEEK) if you need to get through something insane, like a car accident or something.
The anger is mild withdrawal. When you come off clono it will destabilize your mood.
I could tell you all the dangers of clonozapam but then I'd be writing a novel here. Most important to remember are 1) You're impulsive so don't make any commitments or anything you do habitually (like shopping) just promise yourself not to do those things for at least 2 days after administration of the drug. 2) Don't drive or do anything dangerous on a high dosage, it impairs you. 3) Don't ever do it regularly. EVER. EVER. EVER. People have NO IDEA how serious the withdrawals are. Literal torture. Can't sleep for days. Think of the worst trip you can possibly have on a drug, + it never ending, and you not being able to sleep, literally not even for a second, for a week at a time.
You don't want it.
And when you come down off a high dose, that anger thing can be very serious. You may not notice it but the people around you will, you will treat people wrongly, even if you have no idea you're doing it. Clono works on GABA, just like alcohol, and it's effects are very similar.
Also, under the tongue actually doesn't make too much of a difference. Clo acts very slowly. If swallowed, 1 hour til you feel 'something' and 2 hours until it peaks, generally.
Lots of people take too much because they don't realize they aren't in full swing yet.
