I cant be sure but after thinking the opposite for some time, I now think that maybe there is something more nauseating in rue. It was only one particular caapi vine that gave me similar sickness consistantly..and I have noticed it with rue as well but not as bad as with that vine.
I have been working with muricata and it is exactly like the white vine I used to really like..when I drink rue lately I get this lingering transient nausea for hours after the experience ends..it is managable but it sort of makes things unpleasant and takes away from the afterglow.
I cant be totally sure that it was not chaliponga that was doing that though..becasue I was brewing it into my brews for a while..and chaliponga is the least friendly admix for me in reguards to this..lasts longer with significantly more sickness.
I guess I will find out at some point when I brew rue again without any chaliponga..but at the moment the vine I am working with has not given me any lingering nausea after the exprience.
Manske crystals also do this..so maybe it could just be that I became more sensitive to harmaline.
Long live the unwoke.
