I finally got through to the pharmacy and Lo! And Behold! It was all their fault. They didn’t read the prescription properly and gave me the Extended Release as a matter of course.
So in a while, after I have gotten my senses about me well enough to not look like I just got out of bed (which I just did) I will take the Extended Release back to them and trade the pills for the Immediate Release.
At least I don’t have to drive to Vegas in the heat. I have about a third of a tank of gas and the trip would have taken half of that. And I still have eight days before I can fill it again.
Excellent news!
