I might try the tripple wash or at least a double wash.
I'm in the middle of making another batch right now, this one is made with 1/2 Shiva Shanti and 1/2 Chocolate Chunk with a little keif thrown in for good measure.

The headache came on within an hour of digesting, not a hangover. I didn't get the "OGM" results I've read here. Only thing I noticed was the lack of a desire to smoke. Not much of the body high that I read about, I was somewhat disappointed. This is why I decided to kick it up a bit with this batch.

I also read in this post that someone suggested a couple of teaspoons of everclear or vodka added during the last two hours of the cooking process. What is this supposed to achieve? Would anyone do (try) this?
