you'll be fine. i've taken a lot of both at the same time, but i had an opiate and benzo tolerance at the time. seroquel just makes you sleep as fuck, like there's no fighting it at all.
Hey you don't need to make three separate threads about almost the same question. Try consolidating all your questions into one thread that way we can answer you better.
And generally, as far as common sense goes, you should ask questions FIRST instead of AFTER you've taken drugs, just in case what you did was dangerous, it would be too late.
That's a shitload of seroquel unless you've got a tolerance. And why add the diazepam in the first place? You're probably snoozing as we speak
