Hi Quitter- welcome! I was pretty tied into the idea of having a special quit date. Either a significant date or a date where the numbers were significant. like 07/08/09. however, the weekend of Jan 24th I spiraled out of control and suddenly Jan 26th was the 'perfect' date. LOL!!
I know for some people it is helpful to pick a date in the future and then work up to it.
What ever works for you has merit!
