I feel great when I wake up, lots of energy. Around 12 or 1, I start feeling really rundown and irritable and just bad. Then around 6 or 7 or 8 I get another surge of energy and I feel good again. This is an everyday thing. I eat well, I exercise regularly, I drink enough water, and I have a consistent sleep routine. I know I should ask a doc but I'd have to pay out of pocket for any tests they'd run. Any ideas why I feel like this for much of the day? I also take a multi, an allergy bill, and a complex B vitamin daily.
