welcome Budman.  B. caapi changa is the way to go.  make sure you make your caapi leave at least 10x potency.  Then if you want to take that to the next step you can take syrian rue, wait 20 minutes then smoke changa.  This should make it last a little longer(haven't tried yet due to being sick and on antibiotics, will try in 2-3 days though:wink: )
