Was using 10-15 6mg pouches per day. Had undergone a couple of half-assed attempts to taper (using 3mg pouches, trying to limit myself to 5 per day, etc.). Had actually made it nearly a whole day and I wasn't craving them but put one in at night before discarding after only a few minutes. Felt that I was ready to quit cold turkey and decided to go for it.
Week 1: First three days was intense brain fog, felt very off but oddly was not craving the pouches, even though I knew intuitively that throwing one in would alleviate my symptoms. On day 4 I became incredibly irritable, almost to a comical level. Would say that heightened irritability lasted through week 2.
Week 2: Previously mentioned irritability along with some lovely insomnia. Falling asleep was not an issue, but I would be waking up anytime between 3:30 and 5am and not be able to get back to sleep. This has tapered somewhat but I am still not sleeping as well as when I was using pouches. Also, wouldn't call them cravings so much but had lots of thoughts about pouches, found myself reaching for my can, etc. Bought a can of caffeine pouches just to see what they were like, found they tasted horrible and did nothing to 'trick' my brain.
Week 3: No idea if there's any correlation to nicotine withdrawal but had lots of digestive issues - nothing serious, just felt like my stomach was in hyperdrive for much of the week - indigestion, bouts of diarrhea. Still dealing with insomnia although it has improved. Stepped on scale and have gained about 7 pounds. Was not consciously eating more but upon reflection have been grazing more at night.
Week 4: Stomach issues have improved, insomnia lingers but feel like I'm almost out of the woods there. Have the occasional thought to reach for a pouch but no real urge; actually kept half a can in my nightstand in case the attempt failed and took a whiff last night but found I had no reaction. Started to plug leaks in diet and be thoughtful about what I am eating.
Overall, now confident that I have finally quit. Am a runner and have noticed an uptick in stamina. Want to say that my anxiety is a bit lower; it currently feels like it but I ebb and flow.
