You obviously have done the research however if you are using websites they are generally just an overview. Medical databases and medication databases such as MIMs gives you everything that is correct about a drug. I've been doing this for [i]eight[/i] years. Yes while diazepam suppresses the CNS, it does so dangerously. Anyone compromises as I image Virgil would be would actually be at risk of...death. And I imagine since he has the parasite of actually losing more ground with it. 

There is another drug that does the same as Diazepam but doesn't have those harmful effects. It is the same type of drug, I just can't remember the name. I'll have to grab my notes cause it's in those I've just written, which I'll do so after I play with my kitten. I just thought you might like that, and be a little be more accurate. I don't like messing about with diazepam because it is a tricky drug. 

And yes people are different but I can tell you, no matter what person, what condition, what they come in with, [i]every single one[/i] of my patients in my experience across four hospitals and two community health areas who were on diazepam were on it for sleep issues. Every single one has good use with it even after years.

And there is only so much coffee can do to keep someone awake. After even 24 hours awake, your brain and body lose a lot of its ability to function normally. The longest anyone has ever survived without sleep is 10 days. Well that...I'm not going to get into the...let's just leave this at that. Caffeine is a drug. But it only goes so far. Eventually, receptors are saturated. Eventually the body just goes "nope. Time to sleep" and yes I know that that may be different for insomnia, but eveventually the body overpowers that. The body knows it needs sleep. 

Let me just say that there are reasons why diazepam is no longer the number one benzo prescribed 

Oh and it was actually meant to be "I didn't say that middle earth was wrong" the wrong just got...lost.
