dry eye disease
"I started using this about two weeks ago then about a week ago started getting bad headaches... mostly at night...now they are continuing during the day! I am going to STOP using them. At first I was noticing a pressure in my head then the headaches began! I was so hoping this would be my answer as Restasis didn't work for me!!! But I can Not deal with the headaches!!!  Not worth continuing the drug to have to deal with severe head aches!"
