And just to be the devil's advocate here, it is to be expected that one would have an off day or a string of days from time to time, no? I would be reluctant to up the dosage or change it unless I'd gone a good solid month or more feeling out of sorts and 'under' dosed. This is just my opinion only and I'm truly not trying to sound contrary or argumentative (really!) I've had the exact thing you mention happen to me as well, lizzog, only to see it correct itself within a week or so. I'm just throwing it out there. Hugs and good luck!
