I'm curious to know also.
Is there any added strain your heart, but then again why would there be? (Just read that K is not a "downer" and it is a stimulant).
I do remember one time doing some K then eating yellow jackets afterwards. I know it is cheap "gas station speed" but it was rather lovely. I was laid back relaxed but not sloopy, and i was very talkative.
