If the author of this article is reading this : can you please provide a timeline of events? Spreadsheet with column A = date, column B = event, column C = number of hours per day of typing at this point.

Events include {Started Acupuncture, Started using ergonomic product A, EtherPad acquired}, etc;

I wish to exclude these 2 possible reasons for the cure:

a) a simple reduction in the number of hours on the keyboard b) the acquisition of your start-up, which may have released a lot of mental stress
