I think the thing to do here is to not drop your nic level to much, fine tune accordingly so that you aren't wanting to continually vape.
On my hot builds i can probably take two pull's at most just because the 'nic hit' start's to get to much for me, then i can go anything from a couple of minutes to half hour before i feel the need again, an upside to this is that my atty never get's hot and dependent on atty i sometimes go without using a driptip.
I don't always vape vhot builds though lol i have rta's on regulated mod's i vape at around 40-50w, not a perfect compromise but it get's me by for half hour and keep's everyone safer whilst on the school run etc
