The packet, counted
Go back to the drawer. The packet is still there and the count from chapter 1 is still true. Nothing in this book has changed the number of tablets in it, and that's right, because the book's argument was never that you should take them. It was that you should stop deciding about them by a feeling that can't decide, and start deciding with the person who can.
So here's the one action. Take the packet, and whatever else you counted, to a pharmacy this week, and say the sentence. "I've been prescribed these and I've been taking them about half the time, and I'd like to know what to do." You'll get one of a small number of answers. Take them, and here's how to make that easier. Stop them, and here's how. Go and see the prescriber, and here's what to tell them. Every one of those is better than the drawer, and every one of them is a decision that's yours, made with the facts instead of around them.
The tablet is small. The feeling of fine is real. They just have nothing to say to each other, and the sooner you stop asking one about the other, the sooner the medicine can get on with whatever it was prescribed to do, or stop, properly, with everyone knowing.
