I use Refresh Eye Drops during the day. Before bed and if I get up at night, I use Refresh Eye Gel. I use these products that have NO preservatives. This is very important. For my dry mouth I use Biotene Spray, right before bed. You can, also, get this in a gel tube. I do have Biotene Lozenges that seem to help but only short term. I am trying not to take another prescription medication. I hope this helps. These products are not cheap but they help.
