I have a bunch of PT2's, got a Lemo a while ago. It took me a while to get the hang of the Lemo. You will likely be burning through a lot more juice with the Lemo, and getting a lot more nicotine. Maybe you need to get some lower nic juice. Maybe you have the power a little high and the vapor is hotter than it should be. Maybe you need to play with the air flow. Maybe you need to experiment with wicks. The Lemo is a lot different from what you have been using. There are a lot of variables to play with. Like I said, it took me quite a while to get comfortable with it, I like fairly low power and restricted air flow, very cool vape. There are so many different ways to use a Lemo. Just keep experimenting is my advice. Good luck with it.
