Thanks, my eyes are ok. I go to a university medical center and feel I am in good hands. I don't get headaches, thank goodness. I wish I could say I am not "foggy" on a regular basis, but I am. I just posted I have no ill effects from the doxy but didn't mention that I don't see any improvement either. I had long term use of it about 20 years ago when I had Lyme and scleroderma, but that has passed. Or so it seems.
