I'm on Day 13. The first few days were brutal, but I was out of the country for work in a place that did not sell dip, so I had no option but to battle through (in retrospect, that was a great thing). Monster headaches and fog were the order of the day.
More importantly, I know that the triggers and the desire NEVER go away. I know because I dipped for 9 years, quit for 11 years, and then blew it and started back 3+ years ago. It is amazing how easily I justified starting up after being free for so long. Slavery disguises herself quite nicely, and she NEVER lets you go. And even though I can't stand to do it anymore (in the end, I didn't even enjoy but one of every 20 dips I took), I still crave it.
It stops here.
