My mom uses Restasis. It helps her, and I haven't heard her mention anything negative about it aside from the price.
When you say "the doc", do you mean an ophthalmologist or optometrist?
I have problems with dry eyes, too, so I'm always looking for things to help. There are "moisture chamber goggles" and things like that.

Any chance something besides your medications is causing your dry eyes? I have autoimmune arthritis, and dry eyes often go along with that. I have noticed that my medications also affect my eyes, though.
I don't know exactly how medications cause the eyes to be dry. Restasis is cyclosporine, which is an immunosuppressant drug. I think it's intended to relieve dry eyes caused by autoimmune problems. I suppose your doctor should know if it will work for dry eyes caused by med side effects.
I use Genteal or Systane or Rohto liquid tears. They are the best over-the-counter brands that I have found. I still have significant problems with dry eyes, though. It causes my vision to get blurry.
I would definitely use Restasis if I had insurance to help with paying for it.
There are web sites with info. for people with dry eyes, and the Sjogren's Syndrome sites also have good info.
I hope you work it out. Severely dry eyes are so annoying and can cause infections, too.
