Sorry, I usually precise the source
The "guide to a self-chosen humane death" book (2006)
It has a concisely written chapter on benzos. Not overly exhaustive but straight to the point, giving a favourite long and fast acting choice preference with some reason
Was aware it serves as an element in anaesthetic procedures, but that it's also recognised more for its sedation effect than for maintaining full anaesthetic properties against strong pain (death sentence debate with inmates awakening, Midazolam pointed at as faulty), which I guess would not be a concern since SN essentially causes discomfort, not pain
Quarky, source at your turn also please
Disappointing if time is not oral !
If it were valid, it would have been more simple to sequence than with Diazepam, less chance to miss to catch inserting SN intake after first sleepiness signs, at worse not getting the desired effects in time

So you don't have to spend time researching
I hope this book does not contain too much misinformation, because it has interesting stances and developments not found elsewhere. A good complement read to the likes of the PPH
