From 9 P.M. till bedtime my head felt rather confused; I was quite “out of sorts,” and unable too settle to work (first day).

(* He found that our diet had a very soporific effect upon him; indeed, if I mistake not, he got into trouble on one occasion for falling asleep after dinner when he was on duty; he found that a drachm of Guarana entirely prevented this heaviness, and he did not experience that feeling of congestion of the head which, occurs so often after a liberal meal. *).
