dry eye disease
"Initial 12 days were awesome.  My eyes felt completely back to normal.  I did have the forewarned burning sensation and metallic taste in mouth when administering the drops.  However so worth it for the improvement in my vision.  I have now been using Xiidra for 4 weeks and the effectiveness seems to be going down.  I have had multiple bad vision days and had to use refresh drops all day long.  I have also in the last few days starting having an itching sensation in the inter corners of my eyes.  I go back to the Dr tomorrow, hoping Xiidra continues to work but skeptical.  Also I will not be able to continue if the cost is $400+ per month."
