Elderly having severe anxiety/confusion every *second* day at roughly the same time.

My elderly mom has been having some pretty severe episodes of anxiety/confusion over the past couple of weeks.  We've initiated contact with her doctors who are doing their thing, but of course nothing moves as fast as we'd like in situations like this.  

Her life is pretty much consistent every single day, same habits, same foods, same tv shows, etc.  These episodes have been happening every *second* day, in mid afternoon.  The day following she has zero sign of any issue and is 100% normal.  She is on a quite a few meds, again same meds, same dose, same times every day.  The *one* exception to this consistency is her one medication, Digoxin, which she takes every *second* day at 6pm.   I have brought this up numerous times with her doctors and they seem to not be all that interested.   Now despite the fact that her episodes start before her Digoxin dose, and don't end immediately afterward I still cannot fathom how it could not be somehow related... some threshold of one medication crossing with another that at a certain level is triggering.  

No matter what is wrong either physical or mental... I cant see that you'd lose your mind in the middle of the afternoon every second day like clockwork without some sort of external trigger.  And then be 100% normal on the alternate days.

Am I wrong to keep pressing this with her doctors?  I know they are doing their thing but it just seems to me that when you have a correlation like that you'd at least take a look at it first.  Especially in a woman who's such a picture of consistency in everything but that one pill.
