When I started vaping, it was supposed to be an additional thing - for home, so that the house wouldn't smell so bad. After an afternoon of just vaping I tried an analog and tasted so horrible, that I put it out immediatly.
That was it. No more analogs for me.
After over 30 years of smoking, the last years up to 50 a day, I just had to stop because of the bad taste.
I started out with 24mg/ml nicotine (the strongest we get offline in Germany) and felt good. I didn't miss smoking, felt more or less instantly, that my breathing was improving and I could climb stairs without needing to stop to catch my breath.
After six months I am now down to around 10mg/ml nic most of the time. Just sometimes, when I'm stressed or feel the urge, I go back to higher nic.
