Had this issue for years now, meds nuke hunger and I’m terrible at eating breakfast by the time I get back from work they’ve worn off and I have zero motivation. Fallen into the diet of nearly always having ramen, energy drinks and a beer here and then with a muti vitami.
Tried planners, can never get them to work my job having constantly changing shift patterns probs contributes to that, even tried one of those meal recipe box thingies stopped due to it A: being expensive and B: still didn’t really work.
I’m not even a bad cook either just cannot force my brain to bloody do it.
A constantly changing schedule would be detrimental to me cooking, that might be the case for you as well. I need the oppressive clock to say it is time to cook dinner and if the time when I need to cook dinner keeps changing, I will forget to cook dinner and end up doing a quick meal of BS just so I can sleep.
You can also try meal prep, that is just to give you a meal that is as convenient as ramen during the week with a low daily time commitment. The idea of it may be kind of daunting, but it is just a bunch of smaller steps that you can AD4K off between without much issue.
