DHC respiratory depression and overdose

[no more pain]

Hi, I've been registered here for a long time, but I haven't written any messages or comments yet, so I don't have a search feature yet.
I would like to know if there has already been a discussion on DHC / dihydrocodeinium hydrogen tartrate / dihydrocodeine and whether anyone could publish a link to such a discussion.
I am interested in the action of DHC together with benzodiazepines or beta-blockers, has anyone used DHC and had OD?
I use a translator, but I guess it will be understandable

Isn't there anyone who has used DHC? and a combination with benzo? and what would be needed in a quiet way, because the problem is to know what the required dose is
