I'd prefer to vaporize extracted DMT rather than drink ayahuasca.  Don't get me wrong, ayahuasca sounds pleasant and prolongs the experience, but I guess a 10 minute trip is sufficient for me and I don't want to risk the possible nausea that ayahuasca brings on.  Will extract DMT from MHRB one day, I've already posted some inquiries in the general extraction help sticky and am waiting for responses.
