It began late in the day on the 3rd of July, and ended shortly before noon today, the 14th of July.
The experiment was to see how well I could function off of both of my narcolepsy medications - methylphenidate (aka Ritalin) and Xyrem. I had expected to make it only two or three days, but today was the 11th day. I took 10mg of methylphenidate shortly before noon today and other 10mg just a few minutes ago. That's a far cry from the 90-100mg I was taking daily not too long ago.
I'll post more details about how the last few days have been later on.
