I just received my ego kgo today. I've been vaping a bloog maxxfusion before this. My questions are as followed. How long will e-liquid stay useable? Does it get harmful over time? Can it cause abnormal side effects with age? My reason for asking, other than being a slight hypochondriac, is upon receiving this new device, my juice did not come today. I loaded up one of the v2 carts and a ce3xl, with two different juices from gourmet vapor that I bought april 2011. Upon vaping the vanilla gorilla flavor, it tasted actually slightly better than it had (thinking that might be the clearo), then upon vaping the other custom blend (creamy irish mint), i noticed I got super anxious, and nervous. I contacted the company, and they said the juice should still be good through August, but no one has given me a straight answer as to what happens after the juice sits for a while. This juice came with me on a road trip to colorado last summer, 30 days stored in not the "coolest" of conditions, and I guess my primary concern is can it become harmful, or does it actually get less potent with improper storage/age?
