Hi Kellemae! Welcome to the Quit Train. Quitting smoking is the best thing you can possibly do for yourself and your future. You have already heard from a couple of our members here with multi year quits going so you see, it really can be done. I am still pretty new to this quitting thing but I now know that I will make it to being permanently quit.
Yes, for most of us, it's hard initially but it does get easier the more time you put into your quit without smoking. That's the key. Once you stop it's Not One Puff Ever! That's the NOPE pledge. One puff and you are right back to the start again. It becomes a never ending loop of you feeding your addiction. You said it yourself. You break down and buy some smokes then go through the whole process again. You have to just stop period and put up with the early withdrawal symptoms. It will get better and it won't kill you. Continuing to smoke just might some day.
The whole process is very simple. You have to want to quit more than you want to smoke. Easy to say, tough to do but so worth it. Coming here for support is another key to being successful and read, read, read all you can about this addiction because education is key as well. A ton of Videos available here as well.
Make your decision and never look back! Freedom from this addiction is yours if you want it :)
