Excellent decision! We don't mess around here, so no nic means no nic. Period. Dump it all and don't look back.
I used to always be waiting for a more ideal time to quit, but it never came. 20+ years later here I am finally getting it done, and I guarantee I've got more stressful junk going on in my life right now than many other times I passed up the opportunity. Do it now. It will never get easier by waiting.
Read everything you can here, stay close to the site, post your promise tomorrow not to use nic every morning, and be a man of your word. Repeat daily. As many have said before me, not easy, but simple.
