I had noticed last year at this time I would have a headache almost every afternoon. It would make me very tired. It would go away around sunset & I would have more energy again in the evening. I've noticed in the last few weeks this has started happening again. Through fall, winter, spring & early summer I haven't been feeling like this. Just this time of year. I thought I could blame it on being pregnant (19wks) but I wasn't pregnant last year at this time. I take Tylenol, though I can't tell it helps much at all.

Does anyone have any thoughts on this? Why this could be happening? Does it happen to you? What do you do for headaches? Thank you!
