I know they are optional for ctb but they are absolutely necessary if you want it to be as peaceful as possible. Also, you can't count on the sn rendering you unconscious quickly. Yes, it will knock you unconscious eventually. Ideally, in the best case scenario, it will render you unconscious in 15-20 min. However, there have been reports of people (who supposedly did it correctly) staying conscious for a whole hour before finally freaking out and calling emergency services. I would think this is probably because they unknowingly did something wrong...but it is best to be prepared. With benzos there is no longer a concern. A high dose is necessary to ensure this. Also, benzos help to prevent seizures so it lessons the concern as far as that goes. Last but not least, they lower your inhibitions and help to keep you relaxed through the entire process from start to finish... Clonazolam is extremely powerful too so only about .5 should be needed before and another .5 with the actual sn. Even that might make you black out. But you will go out like a light regardless. Plus, there should be euphoria from both the clonazolam in addition to the sn. Should help to eliminate all fear. Next best thing aside from N... Definitely something I feel everyone should take into consideration.
Holy shit, though. 30-80% increase in concentration?? Big range for some reason. And 80 is really high. That's almost doubling whatever dose you took. That's exactly why it's concerning. Granted that is specifically diazepam and not clonazolam but if there was an 80% increase for .5mg you would be completely floored. And of course that is ideal for this situation, but I still feel it's important to know of any potential side effects that could occur as a result of the interaction.
