After a little more than 2 weeks with my e-cigarette my asthma has greatly improved. I was using my inhaler practically after every time I would smoke (10 - 15 times a day), way too much! Now I am using it maybe 3 or 4 times a day and I know that it will only get better. Damn, I can't believe how strong of an addiction nicotine can be. All these years and I couldn't even stop, even if it made my breathing HORRIBLE!. Thank you science for e-eigs. Hopefully I will be able to slowly cut back on the nicotine levels over the next year and eventually I can stop inhaling everything but oxygen.
