Before you're used to your new way of life I would suggest staying away from places where you used to go before and behave un-primally.
Such as the pub maybe. Don't go there until you know you can have one glass of wine, or two and be happy with that.
Or to a coffee shop with a friend where you have all those sweets on display. Suggest going for a slow walk instead, maybe buy the coffee and bring it with you if needed.
I am going to try to stay away from places that will try to lure me back to my old ways, at least until I am a few weeks in and know I have better control over my mind and body.
