If you have built up a "high tolerance" for bezodiazepams...like zanax or valium....will mixing them with alco?

like zanax or valium...will mixing them with alcohol produce death as it would in a person who is NOT addicted? I have seen someone addicted do that, and it only changed him into a criminal while drunk, then he would p out, and not remember anything he did the next day. I am looking for the real painless way to "go to sleep" and NOT ever wake up again...sorry...about to be on the streets...which is worse than death....and will be going through withdrawals at same time....or even worse....in yet another doctor's guinea pig office or ward. It was their drugs and hospitals that led me to this point...a nervous breakdown from pain and sleeplessness....drs. RUINED MY life, my career, my relationships, my finances, everything....cannot even talk to Jesus anymore, WHO used to be everything to me. Heath Ledger found that way out, and he was less than half my age.
