I Am Having Trouble Falling Asleep. My Diagnosis Is Made.

I am having trouble falling asleep. My diagnosis is made. I have tried Ambien years ago and it worked, but I have a high tolerance for meds and alcohol. I was taking 30mgs of Ambien. I have done 12 shots and chased with beer. I walked out of the room. Just some history. I have tried Ambien, lunesta, remeron, diazepam, tamazapam, trazadone, seroquel. There may be more, I just don't remember. Nothing has wworked. I can't get a doctor to understand my high tolerance. I have never done drugs, even marijuana. I am currently taking 120mg of duloxatine, protons 40mg, clonazepam 1mg as needed. I normally have more than half a bottle of clonazepam left when I get my next script so I am not addicted. I am on disability for my smdd. I can barely afford the duloxatine.
