You certainly have my sympathy, I am going thru exactly what you are at this point. I have the plugs, they haven't fallen out, but hadn't felt any relief at all. I started taking restasis 2 wks ago. So far no results. There is a slight burning when I put them in but it doesn't last long. I heard it's at least 3 mos until there is any kind of relief. I also haven't had any of the other type tests. I feel my doctor just isn't getting it. He went so far as to suggest wearing goggles and moving to Seattle. Ok, I'm stuck with Kaiser Dr's, so I'm guessing I will have to complain and complain until I can get another optimologist. I haven't gotten any relief from any kind of drop or lubricant yet. I'm sorry I have no ideas or good news, but I'm hoping someone will answer some questions for you.
