In health terms what almost everyone likes to report after some intervention or action is that they feel better than before.
Each week for at least the first month there will be more better than before moments. As you breathe more easily, and your energy increases, you are better. As your purse or wallet remains much fuller each week, that is certainly better.
You may notice that your brain fog is lifted and that you have more mental energy, this will happen even if you don't realise it because there are many dietary factors involved that can keep the fog in place.
There is however another better than before factor. It's your self-esteem and your emotional wellness. There will be no more hiding your smoking from family, friends and co-workers. No more gathering in a lane way or an out of the way spot in a city or new a restaurant. No more making new smoking friends in a circle around the bin, or having to be out in the heat or cold or rain.
