re: Those that have quit tobacco, when did the cravings stop?

I've never been addicted to anything other than caffeine.

What I've read suggests your cravings should peak in a few days, then subside after a couple of weeks. Generally, the nicotine will have left your system by 21 days. Residual cravings will be psychologically based, tied to both you missing the habit (sunflower seeds, pistachios, chewing gum, etc., should help that) and environmental/social triggers.

I would get a stop watch. When a "no shite" craving hits - start the stop watch - it should subside within 10 to 15 minutes - although they will get more intense and closer together as you pass the crisis point - you will at least have something to focus on - other than fixing.

And remember, almost no addict has ever died from nicotine withdrawal - they've killed others, but never died from their own lack of nicotine.

In all seriousness - good luck and G-d bless.
