I want to veg out

I'm tired. I don't stay up that late anymore and my glucose levels are pretty normal. There's no actual reason why I would be tired. But I am. I eat my vitamins and I have a good rest at night. I don't get up that early in the morning. It can't be age either, because I'm not even 38 yet. But like I said: I'm tired.. I want to veg out, be left alone, get some rest..
