I've been vaping since 1/19/11, pretty constantly, and found when I lowered the nic level, I didn't get headaches like at higher levels. There are many 0 nic juices out there, but remember that any 'steeped tobacco' flavors will contain traces of nic as the tobacco plant does contain nicotine. Vaping is wonderful, isn't it?!
Vaping can dehydrate you, so the only "big" problem is drinking lots of water.
Other than that only problem I can see is mailman stalking.![]()
