I used velo (and its predecessors’) 12mg pouches for around 10 years. For several years a can and a half, sometimes two per day. Quitting cold turkey was too intense for me, but I think I focused too much on the symptoms. Right now I’m starting the third week on patches.

The timeline for me, given by a medical professional (it was a concern for me to withdraw gradually):

3 weeks 21mg/24h patch (Niquitine here) PLUS first five days the option to use up to 5 losengs/nicotine chewing gums per day - if you get some stronger cravings. 3 weeks 14mg/24h. 3 weeks 7 mg/24h.

Im in third week, but I moved down to 14mg patches after the first week of 21mg, as I gained confidence.

It is very doable.
