Welcome sneakyturtle.
Like you this isn't my first try at quitting and like you this quit was unplanned. So I finally have my top 6 newbie tips... been thinking about them...
1. NOPE (or NOPT) - Make yourself accountable by popping into the NOPE thread and each morning and making your committment to NOPE/NOPT for the next 24 hours... that's it just 24 hours, you can do that... then get up in the morning and Groundhog Day that NOPE... the days add up quicker than you think.
2. One Day At A Time - Only worry about the now, not tomorrow or next week of next month... focus all your energy on getting through one day at a time... promise yourself that for the next 24 hours you will not smoke and do everything within your power to make sure that promise stays true. Make the promise to your self each day. Say to yourself, today I will not smoke.
3. Learn - learn everything you can about nicotine and nicotine addiction. Knowing what is causing and driving the craves is what will get you through because that old saying "knowledge is power" really is true.
4. Talk it out - ask questions, rate, rave, rail against the craziness and share it.... chances are someone (or lots of someones) has been there, has felt that, and has come out the other side and because we have we will help you do it too. If its looking dicey, use the SOS threads... lots of us do, have and will again and are still Quit today because we did. The support is amazing.
5 Pre-respond to your own SOS - and when you feel like its too hard, read your SOS response... the other advantage is we can ready it and know how best to help you... it shows the stile of help you like to see... or it gives us an insight into what will motivate you.
6. Be kind to yourself - this is a hard thing, and you need rewards along the way because you are doing a good job. Rewards don't need to be big. But take care of yourself, drink plenty of water, keep your blood sugar up, and tell yourself you are worth keeping healthy, you are worth the effort.
You can do this, stay strong and determined. Hope to see you around the boards.
