Welcome a'board! Cavebaby. Interesting name choice. 'Cause you live in a cave, or 'cause you cave when quitting? Or perhaps you're a spelunker?
So how come the 16th didn't work? Don't be depressed about it, rather figure out why it didn't work and how to make it work! You can. /blogs/Giulia-blog/2018/03/01/quitting-is-a-skill-that-can-be-learned?sr=search&searchId=57ad09f4-35... But you have work at it. And work hard. Most of us with successful, long-term quits didn't come to them first time around. There are some lovely exceptions here, like youngatheart. But for most of us it took a lot of failures before we finally "got it." I'm not sure those failures would have been true for me had the education I glommed onto when I quit the last time in 2006, with the aid of on-line support. THAT is what made the difference for me. Support and education.
Interestingly you will find that many of the long-term quitters here continue their education about this addiction. Whether it's simply out of curiosity as to the new aides and "thinking" that help people overcome this addiction, for themselves and their own quit maintenance, or whether it's to have more knowledge to impart and hopefully enable others to reach the success of a long-term quit - it doesn't matter. But I think there's an ongoing curiosity and interest that helps the successful quitter. If you play a sport, or a musical instrument, you tend to have an ongoing interest in that thing that you're involved with. Same is true with quitting smoking, I think.
Anyway, I waxed on too much. Just glad you've joined our quit family, Paul. READ EVERYTHING YOU CAN GET YOUR EYEBALLS ON. It'll help. Really it will.
