After messing around with disposables I ordered from fasttech, but while I'm waiting I decided to get the Mistic 2 kit from Wal-Mart (since I couldn't find a vape shop near me). It's making me a little upset to my stomach. I've been using it for two days with tobacco flavored cartridges. I've been slightly nauseous and because of this I haven't been eating much but I figure I'd rather satisfy my nicotine cravings. I figure it may be because of an allergy of propylene glycol because I've found that to be common. Has anybody had similar results?
