The only thing I can advise is maybe another form of administration like changa or something. Perhaps the Crazy rapid in your face onset of a perfectly vaped 15-35mg is too much to hold on to after the trip is over. So maybe something with a little slower of a release. Not sure. Just seems like he is trying to go as hard as possible to get the desired effects while not stopping to smell the roses so to speak. If that is not an option, try smoking smaller amounts and sort of build up the experience rather than completely plunge yourself into the madness.
Hope that helps
