I unexpectedly had an opportunity last night to consume chinahuasca. Since I am typically very busy, I seized the chance to take advantage of available time. Given the inability to fully schedule all steps in advance, I could not follow all of the advice perfectly.
I boiled 10g of ACRB for 3 hours, strained the liquid, then put the ACRB back on the stove with completely fresh liquid for another 1.5 hours of boiling. In other words, I only boiled for half of the advised time (i.e., 4.5 hours, rather than 9 hours).
I boiled 3g of Syrian Rue seeds for exactly one hour; then, the seeds were strained out.
I drank the Syrian Rue "tea" 25 minutes before the ACRB (which had some "sediment" included).
At 2 hours and 15 minutes, I vomited; one hour later, I vomited again. 30 minutes after that, I fell asleep for the night.
The vomiting seemed quite late, and nausea was mostly present the whole experience--sometimes it receded in intensity, but it was rarely entirely absent.
The experience was very lightweight. I certainly had routine (not to say unappreciated) psychedelic effects (e.g., what was once familiar now seemed novel, greater compassion toward others, distaste for the artificial, etc.). I also had some visual effects (e.g., slight tracers with moving bodies, etc.). However, I was surprised such heavy nausea was not balanced by greater psychedelia.
