3 weeks smoke free. I have a wonderful sense of happiness all the time

I never thought I would be able to quit. I've tried so hard in the past; this time I did not work myself up about quitting, I just put on my first patch having run out of cigarettes and have not looked back. During the first week i did experience some changes in my life; I felt lethargic, had mood swings and often contemplated going to buy a packet but I pushed through it and I can't describe the sense of pride I feel now, Im on a high. It feels like I've given myself the biggest gift and now I know what life is like. Looking back I can see how cigarettes consumed my life. My days revolved around 'going for a cigarette' and I felt so unhealthy. I am enjoying my life so much now and look forward to being healthy and happy and I will forever feel a sense of pride for quitting.
