I just want opinions here please since I am still new to vaping. My body is used to high levels of nic. I was a heavy dip user for 4 years. Just thought id throw that in there. Been vaping a few weeks and have felt symptoms of too much nic before. It happened with the kayfun and a 12mg juice. I chain vaped it and felt shaky, fast heart beat etc. All of this was a normal over nic experience and I was not scared. I noticed the symptoms, recognized them for what they were, and slowed down on the chain vaping and I was fine. Today something else happened, and this was new. I loaded my Kayfun with Cellucotton from Sally's (Rayon) last night. I vaped it last night for a while with no issues, using the Rayon. Today I was up for a while and got tired late morning, so I took a nap for a few hours. I woke up, sat at my PC and took several good hits from the kayfun. About 1 minute later I thought I was going down. I almost passed out. I was light headed and started to feel myself go. No other over nic symptoms were present that I could notice. This scared the hell out of me and I haven't touched the Kayfun since and I think i'll go back to cotton until I hear other people's input at least. Maybe its the Rayon, maybe not. Perhaps I had low nic levels after sleeping and hit the Kayfun too hard too fast. Maybe its an unknown health issue that was irritated from the nicotine. But for now, I am fearful of Rayon since that's the only thing that has changed before this happened. Thoughts please. Anyone else almost black out after waking up and chain vaping?
