Something I've always wanted to do is drop acid with the express purpose of being with a small group (ideally 3-4 people, including myself) and having an earnest discussion about human spirituality. It's taken quite some time, but I have finally identified a few of my close trip-mates who I believe would be interested in such a journey. None of us follow an organised religion; personally I am fairly lost and looking to gain some perspective through a combination of processing others' ideas and a helpful state of being 
I'm looking for suggestions for things like:
What kind of preparation/action - environmental, mental, so on - would help for this kind of experience?
Where would be a good environment? Somewhere familiar? Far away? Outdoors? Day or night?
What of timing? Would it be best for us all to take a few days off things like work and other commitments before embarking? (certainly some time off afterwards will be crucial!)
Also, if you've ever entered a trip for this purpose, please tell me of our experiences!
