I have no reason to think ChrisC has gone off his meds. I hope, of course, that he hasn't; and that if he has he gets back on them right away. There is no essential difference between meds the mind needs and meds the body needs -- diabetics shouldn't go off insulin. The mind is an organ, just as the heart is an organ, not some mystic ball of pure light.
On the other hand, reading the Tao is no sign that someone needs medication. The Tao is not religion, just good common sense.
