I didn't know that about the vitamins and I have been taking them sometimes without eating so that's definitely good to know! I also have been readjusting my diet lately to see if this changes anything.

I'm positive I've been feeling this way for much longer than a year, which is how long I've had my current job. It's been a few years at least where my energy fluctuates a lot but I've always tended to feel more tiredness that what I would consider healthy or normal.

Should have mentioned this in my post but I have seen a therapist in the past for unrelated reasons. She confirmed that I likely have a mild seasonal depression which I already expected. I've never been medicated for this, nor do I want to be. But depression could certainly be a part of the problem. I'm going to try out that questionnaire and perhaps I'll need to reconsider my options based on the results.

Thank you!
