Hi there, new vaper from Singapore. Been on analog for the past 20 years and 2 months ago, I had a chest and back pain for which an ECG was done. Turns out that the analogs and my work lifestyle was killing me. Made some research on NRT and came across e-cig as a potential alternative (I had a janty set many years ago but flicked it out and totally destroyed it). Thus here I am, armed with a KF and a provari mod and life has been literally breathable then. Would love to contribute more here.
