Well, it did not feel that bad. It was more like "It needs to get out so I can feel better", not "real" nausea in the sense ob beeing sick. I guess that's tolerable. First a small bowl of caapi extract (made with IPA) was smoked (from a failed bufo extraction, so trace amounts of bufo might have been there but no indications, no constriction). This left a strong IPA taste behind. Felt very unhealthy. So the it was decided to lie down with the VG and some spice quickly melted on some unenhanced vine. At this point, a glowing feel was already present.
The following mild experience can only be described as a slow drift into a world made of full body massage and well known patterns and places. It was also a bit longer than usually.
Oh and it is somewhat hard for the Spice taster to gauge the amount of heat needed while under the growing influence. At some point, it's better to stop the flame and to just draw.
