The questions I have, your chain vaping. Do you feel like your not getting enough Nic, or do you Feel like your set up is just not the same feeling as your Cig??
What I did, is I set down with my set up, lit a cig, then compared how it felt compared to the cig. There could be countless reasons your chain vaping. I would start with, ok, my set up comes super close to how a cig feels to me. Once you get that done, and you find yourself still hitting it way to much, up your nic content.
I am a mouth to lung, found that the baby beast, wide open, q2 coil cranked up to around 50 to 55 gives me the closest feeling to how a cig hit. I started with a nic content of 18 mg, and I just now dropped to 12, see how that goes, if it fails, its back to 18 I go.
Another thing, is learning how to vape correct. Vaping is not a cig, you wanna take your time. Take it slow, Take it in, hold it in your lungs for just a bit, then when exhaling, blow most the smoke through your nose, it will improve the taste, and they claim the nose can absorb the nic better. It take a bit more for the body to absorb the nic from vape. So keep that in mind. Nice, Slow, take your time, hold it in your lungs a bit, exhale slow, through the nose mostly.
So imho, the first step, try and get your set up to come as close to the feeling you get with the cig the best you can. Is it warm enough?? Are you getting the lung hit you need??? Let us know.
One final thought, with vaping out side in the cold, now that can be tough. YOur bringing in cold air, and its not gonna ever come close to smoking a cig outside. So try and keep your mod as warm as possible. It may be you really need to crank up your wattage to get that warm feeling while out side. Just a after thought.
