I got me some Heavenly Blue over azareus (and some HBW from there too, and Shayanashop), but didn't wash them at all; just chopped it up with a good mindset, seeped it for 30 minutes in hot-ish water, then downed it. Definately didn't taste like peanut butter, I'll tell you that! Hah. Didn't experience any nasuea either, although the trip easily outripped any LSD trips I've had, mostly because I really let myself go, then strained myself, ultimately leading to a Bad trip, ego-death and revival and that whole shenanigan (it was beautiful!) The night before my morning glories, I did HBW, however, which made me puke up a ball of white slime. I figured my stomach only found some of the toxins which it really didn't like, made me puke it up, then made me crash in an intense body-feverish state which even cannabis didn't help against. Mind/head stayed on top, though, and together with some psi-trance, I soon could wiggle a finger, a hand, an arm, a torso, then full-on dance. Pretty groovy.
What struck me as truly remarkable, HBW and Morning Glory between, was the difference between the 'feel' of the high. HBW was way up in the head (above it, actually), while MG was located in the gut. Made for some truly interesting trippy times.
