By much higher risk of death, do you mean risk of suicide?
Also, I've tried "rubbing one out," if you will, and even when my shit does work, it's often painful, and rarely has any effect on my ability to fall asleep.
any sources to back this up? if i could be really sure about this i'd go back to daily therapeutic benzo use rather than struggling to get through constant panic attacks.
for OP: have you tried taking 50-75mg of diphenhydramine (higher doses will keep you awake and restless) and a lower dose of a hypnotic? I do 50mg-75mg of dph along with 3.75 mg of zopiclone and if i'm not too high or caffeinated i can usually get to sleep and stay there. I've had insomnia my whole life as well and it has kind of defined my existence so i know what it's like. Without the zopiclone i will have a massive panic attack every single night when i go to sleep and it is shit to live like that. It just relaxes me and takes away bedtime anxiety so i can fall asleep, doesn't really sedate me.
Sleep hygiene is also very important as is adjusting your daily schedule so that is more in line with your natural cycle.
