This is not at all stupid! I notice differences in myself depending on diet. The biggest factor to me is, I wake up from nightmares and then I don't get hungry all day. So I don't eat, and that definitely affects my mood. It's a bit of a problem. If I have to drive somewhere, I force down a granola bar.... but it has made me hate granola bars. I don't want to switch because I'd probably develop an aversion to whatever other food I tried! Right now I'm taking an antibiotic and I need help from my family to make me eat something when I first wake up to take that medicine.
I should do this every day, antibiotics or not, but it's hard to eat when you're not hungry. However, when I do it, it generally makes me less anxious and simply allows me to experience my day in a more positive way.
Another food-effect is, when I'm suffering from insomnia. Sometimes something sweet helps me over the bump and into sleep. I think protein helps me most of all but I think it varies a lot from person to person.
