Hmmm strange....
I actually had my first noticable effects with chaliponga after the third time, i guess.
I blamed it on my brewing skills, however, it might be some sensitization process, who knows
For me, I came to like the mix. It really can be a very very rough ride if you overdose, but to get to know the plant is very worthwhile.
Anyway, keep us posted, i'm interested to hear how it works out for you...
