I have had dry eye for 20 years and have been using Lacriserts until Merck had a "unforeseen manufacturing problem" recently. I have found that the following combo of OTC products works pretty well for me: GenTeal gel every 4 hours or so, Celluvisc 1% every 2 hours, and Refresh drops or TheraTears pretty often (every 15 minutes for me). Good luck!
