On friday night, teach a 1 hour salsa class then go social dancing for 2 hours. On saturday, go for a 4 hour walk around Castle Howard. On sunday, forget to have breakfast or lunch, teach a 3 hour salsa class, cram a pizza and social dance for 4 hours, all in summer heat.

Don’t expect to wake up feeling at all hydrated.

I had lost something like 3 or 4 pounds when I weighed in in the morning, but I seem to have put most of that back on again now.
