Hi @marie-quit congratulations on your choice to quit. There are quite a few of us who have or do use NRT gum to help in the early days. I agree 100% with Weegie read and watch everything.
OK.. I am 4 months smoke free and 6weeks NRT free. Firstly while I have anxiety and panic attacks I am not medicated, if you are medicated I suggest seeing your doctor as doesages of meds may need changing during your quit. So honestly, the first few weeks are hard but by about the 10 week mark I had noticed a huge improvement in my anxiety. So once I made the decision to quit I set a plan for how long I was allowed to use the gum and how I would use it. I was a heavy smoker (+20 a day) and so I started the gum on 4mg...but even still I would only allow myself 6 a day, I would gave normal gum in between and I would wait as long as I could until i had the first chewie if the day. After a week I switched to 2mg same rules, 6 a day max, hold off on that first one as long as I could. I had a plan to allow myself to use NRT for 3-6 months with a decrease in the # a day max on a regular schedule... Thing was I was using it less and less and for me, halfway threw month 2, I realised I hadn't had one in 4 days so I handballed what I had left and have been nicotine free since. The first week or 2 post NRT the anxiety was a bit more like it had been during smoking but now its the best its been in years. The 2nd biggest tip is everyone's quit is different do wot works for you because wot might work for one might not work for another, do what works for you. There are always peeps around here who have experienced what you are going through and will be able to help.
The single biggest bit of advice I have, take it one day at a time. Focusing on 24 hours smoke free is much less daunting than a lifetime but all those 24 hrs add up and soon you will look at a calendar and say wow there are a 100 smoke free days.
Best wishes for the strength and determination to achieve this.
