Nicotine was a medication when I was undiagnosed, for over 30 years, on and off. I would stop for a while and then small dose here, small dose there, and back at somewhat regular smoking again.

After diagnosis I looked things up, realized why I smoked and that I have better meds now, stopped permanently one day shortly after. Weirdly, no fuss and the nicotine withdrawal hasn’t been a problem.

So, so much freer and cleaner and I have my sensitive sense of smell back.
