First of all I know what you mean about being self-conscious when you first vape in public. I too was self-conscious. But please remember that you are doing this for you HEALTH and as importantly, please remember that "Smokers of analog cigarettes" also tried to hide that they were smokers. It is this reason, I believe, that smokers lost their "Rights" to smoke in restaurants, bars, within 20 feet of any door, etc. It is due to this reason, I quickly lost my self-conscious about vaping. Now I vape anywhere I want, even in the Doctor's office! Unfortunately, nobody has approached me to tell me I can't vape where I'm vaping, because I've got about 3 months of pent up anger that I am willing to unload of the first person that does!
