I smoked for 15 years. I attempted to quit dozens of times, I tried every product offered on the market except for Chantix (predisposition to depression, doctor recommended against it). The patches, even at the lowest level made me so sick that i was throwing up after 4 days of use. The gum made no difference. I never made it more than 4 days cold turkey before my friends, family, or coworkers would buy me a pack of cigarettes so they could deal with me. My life changed when i found personal vaporizers. My health has changed dramatically, i can now breathe, smell, and taste again. My life has changed for the better, and I have no doubt that with my continued use of personal nicotine vaporizers that this pattern will not change.
