Yes. you can get a good coconut oil at the grocery store or Whole Foods. I can't find my coconut oil to give you the brand name. Yes, it should help with the dry mouth at night. You can do the pooling more than 1 time a day. I was told this by a dental hygenist. It also kills bacteria in the mouth. I agree that your meds are causing the dry mouth. Biotene mouth wash is also good for dry mouth, drinking lots of water is good as well. I have the opposite problem...hyersalivation! I could open my mouth and water the front yard. LOL! Medication is a double edged sword with the side effects isn't it? You have a blessed day!
