Quit #2

I quit last year on February 1 and lasted for 5-1/2 months. I used the patch for a few days then, but couldn't sleep, so I stopped that. I have been smoking for 45 plus years and that was the first time in about 20 years where I had managed more than a few days without smoking. My doctor says not to be too angry at myself for starting again after 5-1/2 months, but I've been smoking a bit more than ever since. Has anybody on this site been smoking for this long, and if so, do they have any advice?
