I am sorry you never received an answer, 1 because I know what it means to need some help when you don't feel well, secondly bc I now have the same symptoms. I need to get to the bottom of this.
I do drink alcohol, have taken advil .. not consistently, drank some soda but not really in my life. My brother has the same thing, but hardly ever drinks alcohol, never takes advil or aspirin.
The only thing I consider, is that both of us have what I guess is toenail fungus, it does not look like fungus, but shows up as lines on the toenail. We have had this since we were kids, my sisters do not.
