I started 3 months ago with Nautilus mini, Atlantis and the CF sub ohm. Quickly picked an istick.
I thought the Atlantis was going to kill me. Couldn't hit without choking and coughing. Lung and throat burning hacking. The nautilus was also a bit choking, didn't give me enough mouth feel and would get burnt quickly.
I was allergic...I got a bad unit... This piece of gear is junk...I'll never get off cigs... If it's not burning, it's gurgling... Arrrrrrgghhhh!!!
Nope. I was vaping like I had smoked. Strong short draws, mouth to lung in quick succession . I was either drawing to much liquid into the wick or sizzling off liquid faster than it could keep up (mostly the latter).
Slow it down a bit. Think about smoking a pipe. Longer, steadier, softer draws. Even if you aren't getting the coughing reaction I was, you might still be getting used the new delivery system. After a couple of weeks, I found that I wasn't burning a coil head everyday. It just sorta started working better.
Another handy tip: put your finger over the airflow hole and suck. You'll probably see a bubble or two come up from the bottom of the tank. That means more juice just went to your wick. Try that when it is starting to not taste or feel right and you catch it before you get to burnt.
