I've had severe insomnia for years so bad I would go days without any real sleep, just resting in bed. I started blacking out when driving even though I took back roads and was super careful knowing I was impaired. I still had a very close call, looked both ways and pulled out right in front of a car. I knew I had to do something.
Don't use benzos, they are only good for short term, are highly addictive and have nasty side effects. I found several things that worked with just minor side effects. MJ is good for sleep, the bad thing is it loses its magic if you use it frequently and you need more or take something with it, maybe kava or what not. Most nights it will get me to sleep but not if I'm wired up over a project or new concept.
Mirtazapine knocks me out when I use micro doses once a week or 10 days. More often and it loses magic fast. I need only about half a mg to do the job. Another one that works well is seroquel, small doses again and no more than once every 9 days. Then I have etizolam, works very well, not as bad as the benzos since it isn't one but can be habit forming and tolerance. I need only about 1/4 mg to do the job.
Any of those can give mild groggy hangovers the next day, depending on dose. Thing is what is worse, a hangover or not sleeping and dying? Even if not dying, severe insomnia makes life hell and might make one want to die. Pick your poison. Using things less often means they keep working. Right now instead of pot 5 times a week I want to be able to cut down to no more than twice, which keeps its magical feeling and sleep inducing charms. I have some herbs on the way I plan to try. Nothing that has been mentioned.
This system has worked for me for over a year. Sides include short term memory loss and occasional groggy feeling the next day, mostly from the mirtiz and seroquel.
