I’m doing a gradual quit with replacements. I know I’m not getting the level of nicotine I did when strictly smoking. My concern is from some reading I’ve done is there is withdrawal from the other addictive stuff they put in the cigarettes. I can feel the withdrawal in so many ways now that I have dropped from 15 to 4 a day. This isn’t a good time to quit (many emotional issues like becoming a widow, birthdays and holidays coming up alone) but I’m on oxygen so have to do my best. Any input appreciated.
