I am so sorry for your lose. Certainly a combination of drugs, especially the ones he ingested, could cause his death but you will need to wait for the autopsy report to know for certain. I know this will bring you closure and that is important in this case. I hope that you find peace with this, no matter what the out come. I will say a prayer for you.
Hey hun. Im sorry your brother had passed away. Im not a dr. but I was a long time drug user/pill head&been on alot of meds due to mental issues,,about two ye&rs ago I was in a simalar situation,i o.d & died,was lucky enough to beput on lifee support. The xanax bars mixd with any other meds 'specially be/adryl can cause respritory problems,and u said hes been doin it for sumtimr now,i believe that it finally took a toll and he passed in his sleep. If it was a dr. prescribing all the meds u need to file a lawsuit hun.,let me kno how things go. Annie.
