"Don't blame me. They needed to be used by the expiration date, and you don't like them, so I was hardly going to let them go to waste. And I'm pretty sure my meds are somewhere between here and the hospital. They'll turn up, eventually."

Addiction sucks, for all involved. I hope he finds the strength to change.

That sounds more like an F his life, since not only did he lose 6 toes, but seems to have no self control when it comes to taking care of himself.

From her FML it kinda sounds like he deserves it though...

If you’re in a non-shite marriage, an FML for one spouse is an FML for the other.

FHL. He doesn't seem aware of or care about the consequences. If I lost that many toes I'd reconsider my life choices here.

I hate to say it, but if he keeps this up, he's probably going to lose a foot next.

Interesting that he doesn’t loose the bag of sweets but the medication one

It's obvious you care about him a lot, OP
Have a serious talk and tell him how it's affecting you and his health
Talk to him about getting help he clearly needs

He’s just celebrating with candy that he has four toes left...for now.

I would recommend you to go to YouTube and search for Jason fung or Dr berg and watch some videos about intermittent fasting. It might help your husband.

Or it might help not or even endanger his life. Not all patients with diabetes mellitus (especially those with type 1 and/or treated with insulin) will benefit from (intermittent) fasting. Fasting in such patients can lead to hypoglycemia (low level of blood sugar/glucose) , which can even kill the patient.

Leave, before you're stuck with paying for his permanent hospitalization

Yep, the next thing to go will be his vision, or his feet.
