I'm vaping too much (well too high of nic) when I get dizzy and my heart races and I get the sweats. I like to try and vape enough that my girlfriend can't see the TV, we have a big room with a fan on high and window unit though so the best I've done is the kids saying it looks like our rooms on fire from outside in the hall. Some people like a cold beer every now and then or a glass of wine as they relax and put their feet up at the end of a long day. For me, I like to drip some heavenly juice and kick back with a big ole smile on my face and think "whew, what a day. Been thinking about this drip for days!"
