I'm sorry to hear friend.
Unfortunately, besides Benadryl, Ambien and possibly marijuana, I don't know too much about possible sleep aids that can be helpful.
Have you ever visited a sleep specialist for further workup? I've heard of sleep specialists having their own sleep labs, whereby patients stay for 1-3 days while they are monitored through their periods of sleep.

I initially used marijuana for about a year, it was pretty effective, but it tends to make me lazy and I developed a pretty bad cough (I was smoking it), so I stopped taking it, the doctor gave me some anti depressants, but they just amped me up and that's what triggered the whole sleep issue. I was diagnosed with PTSD after the Pitbull attack (due to the length of the recovery I had to sell my business and specialised equipment and I made many changes in a short period of time, some by choice, others not so much), but I didn't think much of the initial diagnosis, at first I seemed unaffected but after a while the effects were pretty obvious, I became a staunch breed restrictions advocate, researched the issue relentlessly, created a website and had regular contact with other advocates and wrote to politicians etc. I eventually scaled this back to just a facebook page as the abuse, death threats and insults become too much for an advocate who has been personally affected by the issue. You only have to look at the people here who don't like me, they often like to taunt me using the pitbull attack as ammunition, although, I have grown immune to others personal insults and feel confident in my position and views on the matter.
The main issue I now face is dealing with the seething RAGE I feel about the incident and how it all happened and the owners response and particularly societies lackadaisical approach to dealing with such matters. I lost a lot of money as a result of the incident, and after three years, I am still waiting for the court case to start and apply for some form of compensation, not to mention my left leg is permanently fucked and causes me all types of pain and discomfort. Before the attack, I used to have the usual amount of restraint, now, somebody triggers me I am ready to kill (literally), and the scariest part is, I don't care. When I get like this, I feel like I have now gotten in touch with a side of me that has a death-wish. it's not that I want to die, IT'S JUST NOW I am prepared to. I think after the attack, I lost any tolerance I had for fools, and that was low already. Unfortunately for me, their are plenty of fools walking around. I have just accepted that it will be a long slow process for the mind to settle again and for my life to stabilise, things are SLOWLY coming together. These days I am Aiming for progress and not perfection.
