I've been fighting to keep a headache at bay most of the day because I woke up to a comment from a reader that just...tensed me up. Irritated me first thing in the morning and when I get irritated...it's hard to keep a nice mellow relaxed mood after that point. 
So it's been hit and miss. I feel the twinges of one beginning and take actions to get rid of it...which it does only for it to again twinge a bit later again trying to come back.
