I totally agree. Substituting one sweet for another does not solve the real problem, which is cravings.
Fasting and having a clean diet helped me rid the cravings. It took many weeks and a super strong will.
It all became easier when my ex-wife died of complication with type 2 diabetes and I was diagnosed with pre-diabetes.
It was life or death for me and in that case, I was fortunate.
Every day I am crave it a lot less. I am very motivated to not relapse because I know how difficult it has been to get to where I am.
