How are you dealing with dry eyes?

Recently, my eye doctor asked how often I use my Thera Tears and when I replied many times a day, he told me I have dry eyes and should not be using these eye drops more than 3 times a day. He gave me a sample pack of Xiidra which has single-use containers and has no preservatives. I quit using them because it felt like I had been injecting sand in my eyes. The prescription for these single-use containers is $300 for 90 days. I asked my pharmacy to hold that RX because I was not sure if I would ever use these again. What do you do for dry eyes?
