So it's like a promotion, right?

I refilled my Xanax yesterday and Tom ran up to the pharmacy to pick them up for me. My pills have always been little ovals scored down the middle for easy breaking should I only need half but this time they were pentagons with no such score. In fact, they bubble out in the middle which would make breaking them impossible without a pill splitter.  So I googled and found out that I now have extended release Xanax instead of regular Xanax, but in the same dosage. But I don't know why my prescription got changed.  I am choosing to take it as a good sign, as a progression. I've been bumped up, like a promotion at a job. I expect a raise in pay to come any day now.
