Apparently the ecig without the nicotin does the job for me. I like to fill my lungs with smoke and blow it out. But ecig are difficult to access in Australia. So its easier to smoke cigarettes. The stressfactor having no substitute is tremendous and i smoke more. X+ hits a day.
I vape with 9 mg. I need to refill it three times a day. The tank is 5 ml. But I always let like 2 ml in the tank. so between 9 to 10 ml per day of liquid.
I use 18 mg vape liquid, 2-3ml a day. I picked up camping after 4 years not smoking and feel no different than non smoking but have calmer nerves than vefore. Except here lately I have a lot of panic attacks.
