Hey, another crazy nurse!
I had the same problem as you when I first started
vaping. I was a deep inhaler when I smoked and I tried to vape the same way I smoked, with huge deep hits. If the ecig can't vaporize the ejuice as fast as you pull, you will pull in
juice with the vapor.
One possible solution is to change the way you inhale. Try soft slow even puffs and make them shorter. This didn't really work for me. I'm a freaking hoover and I inhale hard and I couldn't change that. It's just gotten worse since my lungs have healed up and now I need an ecig that can deal with my massive puffs.
Instead of adding more nicotine, you probably need higher voltage and lower resistance for the ecig to keep up with your inhalation style. This will create a warmer and more satisfying vapor and you will stop getting
juice in your mouth. Really strong tasting juices with lots of TH can help too. You can pm me if you have questions about any of this.
Good luck to you.
