Im not a doctor i really cant say. But i take modafinil and used to take benzos and never noticed any addictional effects beyond 200 mg of modafinil. And modafinil unlike say amphetaminepstly just make me awake. So taking benzos and a drug to be alert sounds like it just is a waste of benzos too.
I don’t see why it would be a problem. And luckily 60mg temazepam isn’t that high compared to recreational doses, not that I’m suggesting you should take any more either.
Why take the temazepam though? To help get to sleep? That’s probably all it may be good for, I can’t really imagine it would produce an enjoyable buzz or anything.
