I use an E cigarette too and haven't had any problems with fish as a result. I did not smoke in the house but I do use the E cig in the house, and occasionally in the fishroom.
BTW, I quit with the E cig almost 9 months ago and I never looked back. Congrats.
Congrats and thanks for sharing. We'll see how it goes. The ecig is working for me so even though, ultimately, breaking the nicotine habit would be nice, just being away from the smoke is great.
