I used to chain smoke Nightcap all night while writing in collegeI think my record was like 10 bowls in one night while writing about current events in the middle east...Not to mention I would semi inhale back then too....
No wonder I struggle getting a Nicotine hit.
I concur on the 60%-65% RH. I like mine arounf 63% myself. Keeps decent flavor and eliminates burn issues.
