Hi, Justanothermind, welcome to PsychCentral (PC). I would go to your primary care physician and have a full checkup, especially your thyroid/other hormone levels, various vitamins (D comes to mind and B12), etc. Make sure there aren't any other problems, maybe even go for a sleep study? Make sure that no one thinks it could still be related to your "poorly managed" diabetes. You have seen that things have improved as you have improved that somewhat, maybe it takes time and/or there are other things you need to do with it besides just diet/drinking so you don't have to get up to pee -- which comes back anyway, no matter what when you get older -- I'm turning 64 and have a somewhat similar sleep pattern as yours but I am not sleepy during the day/don't need a nap; that sounds suspiciously like sleep apnea.
