congrats on the progress and finding what works for you.
yes it gets easier as days go by but remember the acute phase of your withdrawal is still in progress. people used to say 3 weeks. i had it last only 2 weeks. for some it might be more.
i also forgot to post this the other day: chewing gum, because it's actually a repetitive exercise, increases serotonin in the brain. if you have dental issues this might be a problem, but if a sugarless gum is something you can handle, it might be a good substitution for things like reading and driving, actually.

plus, if you need the caffeine as a drug without the smoke trigger, there's caffeinated gum for a one-stop stimulant shop.
