Meditation experience helps a ton! I tell anyone thinking of doing mushrooms/lsd to start meditating for 20 minutes to an hour a day.

Meditating an hour or so before ingesting your substance of choice and then continuing to meditate until you come up helps to ease the stress of going into a trip.. Stress and trips are bad so making that as limited as possible is always good. Set and setting are key here.

Probably worth pointing out that stress is actually fairly rare (one could think otherwise from your comments). But boy if you encounter it, being pre-prepared for it is a very good idea.
