Anxiety/Depression Medications and LSD

There are a lot of mental disorder medications that can decrease the effects of tripping on lsd (mirtazapine, SSRI). I'm just wondering if anyone knows a medication that doesn't affect the trip at all. Only LSD or shrooms, I don't care about mdma. Thanks for any help.

Personally half the time I think anxiolytics and/or anti-depressants should be dropped and something like LSD should be used a few times in their place (but that is just me).
