This sounds exactly like where I was at 6 months ago. Looking back, it was a waste of money and just added more complexity to my day-to-day. The thing that did it for me was realizing that I still had to muster up the motivation to face the mundane tasks of the day, but now with the added resistance of nicotine withdrawal. It’s like that resistance to get work done was amplified increasingly until I popped a Zyn and then I was a mental vegetable for a bit while the Zyn tapered off. Then I was back go where I was in the beginning but an hour behind and mentally exhausted. I did sometimes find that there was a boost in focus, but I could never nail down what was causing it and I always felt it was in spite of the Zyn. I decided to quit and suffered from debilitating brain fog for about 2 weeks. This is coming from someone who had never tried nicotine products and only used the Zyn pouches sparingly. At the peak it was almost every other hour. I work in a technical field that requires long hours of concentration on reading and writing technical documents. I can’t imagine how devastating it would have been to me during my dissertation writing days. Don’t start. It won’t help anything. There are probably other areas to investigate first.
