Personal Story: There have been times when my pdoc, who knows me well, has prescribed either an additional medication or a deliberate overabundance of one of my standard meds to take as I feel the need.

Having something more powerful on hand only for those rough times might be an option in your case. Of course, were one to use the "extras" too often, it could initiate a cycle of diminishing effectiveness for those meds.

Wishing you and your doctor a profitable appointment!
