Alcohol was a real pain to cut out, although it's been some years now.

I've tried many times to cut out chocolate, and managed for up to 6 months at a time before coming crashing down. A few months ago I switched to "mindful eating", which says I can eat chocolate whenever I want, and life has been better.

As long as you're eating dark chocolate when you do, you'll be fine.

And becoming a bit snobby about chocolate helps as well. Single plantation chocolate is delicious (and for obvious reasons dark) and their prices make you want to eat less of it anyway ;)

Can't speak for your parent, but cheese seems to be a major stumbling point for a lot of people.

Sure. Bread. It's so convenient and easy, and it shows up in 90% of the things that you might be able to get for breakfast and lunch at the average food joint.
