I have been getting at least 2 uses from a load, I have been starting on 3 to keep the heat lower, and vaping what I believe to be about 1/2 the load, and if I find it's working a few hits in, I stop and turn it off, pulling the last hit after I turn it off to cool it faster and get the last bit of vapor that's left over. Then I'll go back to it, and put it higher anywhere from 5-8 to finish off the load. I like the step up process I learned from the Pax. low heat to start, med once that gets unproductive on low, and high to finish.
I actually went through much less of my meds over the weekend than anticipated.
