I have been dabbling in vaping for a few weeks now. I began with the intention of replacing analogs. I really want to give up those nasty, stinky, cancer sticks. I've purchased a 4081 with manual and auto batts, a Kr8 system, and now an Ego system. I really like the ego, but I cannot give up the analogs. I have spent hours reading through posts on this forum and have read countless posts of people receiving their pv's and never even wanting another analog. Many of these people didn't even intend to give up smoking when they bought their first pv. For some reason I still crave analogs off and on throughout the day. Also, I have numerous juices already - different nic levels, some only pg, some only vg, and some a combination. I can't seem to find a juice I can vape consistently without coughing and having lung discomfort. I try higher nic levels to try to overcome the cravings, but the coughing gets to me, so I go to a low nic level and it feels better for awhile but then starts up again. I ordered 100% VG because I thought that it was the PG that was bothering me. I still have coughing spells if I try to inhale. I have tried holding the vapor in my mouth and then inhaling, but that doesn't seem to help. I vape and then exhale through my nose and that does help, but doesn't really replicate smoking. I have read that some people are very sensitive to PG. I don't know what else to try.
