Insulin resistance new start

Hi, I'm going to be turning 50 this year. I've always struggled with my weight, it's been up it's been down. All through my life it seems I've had an endless parade of well meaning but ultimately useless diet advice and felt like a failure and a terrible person, how may times have you heard it's just will power or experienced downright contempt over your weight. Labelled fat, greedy or lazy? Then in December I was diagnosed with type 2 diabetes as I'm insulin resistant. So I'm going to turn this around and lose the weight for good and see if I can reverse this condition.

I was prescribed metformin, within two days of starting this medication I couldn't believe the affects it was having on me. I can only describe it as like how you can sit in a room with an AC or electrical buzz that you don't notice until it's been switched off, like that but with the constant sugar and carb craving gone. I don't know weather to laugh or cry, it's like I've been gaslit my entire life into believing it's because I've lacked the willpower to get a handle on it, with proper glucose regulation I've found I don't want the snacks or copious amounts of sugar; I haven't had to fight my bodies cravings from a metabolism that was broken. I believe you are locked in a cycle where your system cannot regulate sugar or use it correctly so your body craves it constantly, like a thirst you cannot quench this locks you in a cycle where feeding the cravings just adds to the problem. With the cravings gone it has been no issue at all to change the way I eat, I'm three weeks in I've made substantial easy changes to my diet that I've never been able to do before.

Don't know why I'm laying this all out here, just wondering if anyone has had a similar experience.
