SWIM has used chaliponga with pure harmine and didn't get any nausea at all. He used 200 mg of harmine. I don't recall the amount of chaliponga he used, but it was the normal dose. This was all oral, nothing smoked.
I've heard that smoking harmine/harmaline is not effective for oral DMT/5-MeO-DMT. But SWIM never tested it. Maybe it works.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
