Why I am tired....

... the return to a different routine
... much more noise and stimulation
... ten hours spent in school over these first three days
... poor sleep
... extra taxi duties for the girls (5 hours driving over the last three days)
... lack of quiet space
... being woken by the alarm at 6.30 each morning
... therapy session yesterday


So I guess I should stop (a) being surprised at my tiredness and (b) beating myself up over it!
