When I got the prescription at my checkup, I still had 2 months left on my old one and couldn't fill it yet. When it came time to fill it, I had misplaced it, so my dr's office called in a refill, but only called a partial one in, not the full year. I only have 1 refill left on it. In the meantime, I found the original prescription and wanted to just take that to the pharmacy instead of asking the dr's to call in another partial (which is like pulling cemented teeth to get them to do).
