I had the same problems awhile back. I would go into the Dr's office constantly thinking I had pink eye. I was prescribed drops too. At the time I did not have insurance and it was costing me $100 a month. I found an over the counter alternative though. They are called GENTEEL drops. They have them in a couple of different strengths. These work for me just as well. Also, the best advice I ever got was to change your pillows every six months. They tend to build up dust mites and that may be what is bothering you. Hope I helped a little.
