I've been rotating between different e- cigs and I seem to be getting sick. The first is a nimbus clone with dual coil (.35 ohm) set up with a private v2 clone mech mod and the liquid i'm vaping outta that one is hawk sauce 0 mg nic/ 20/80 % pg/vg, (beast vaping that one steadily). The second is a standard battery with a ucdt carto/tank and in this one vaping Uncle Junks "bettie white" 12 mg nic/ 80/20 vg/pg. The third is a innokin cool fire II, (the grenade) with the same kind of UCDT set up, carto and tank. In that I've gotten virgin vapor's Georgia Gold @ 100% vg and 12 mg nic. I may be over doing it. Have been sitting around alot and may just need to get out of the house a bit to excersize or do some physical activity. I don't think it's the vg and my nic levels do not exceed 12 on anything. Had to switch to 0 nic on the RDA because it was way to strong with any nicotine in it. Anyone got any suggestions as to why my throat is swollen and itchy?
