In my case you're 100% spot on with the unhealthy relationship part. I lost around 45kg in slightly less than a year and gained most of it back in the 2 years after. For the most part, it's due to really bad habits built up over years.

Addictions are interesting things to break - I suspect they're also very different based on the person. I smoked for close to 10 years before going cold-turkey from 3 packs a day yet the nicotine cravings I had doesn't come close to how badly I crave sweet stuff most of the time.
