I've never had significant problems with sleeping beyond the occasional restless night or early waking. But this year I've had two recent but different episodes of insomnia, one pre-CLIPPERS and one current, which go beyond simply "not being able to sleep". I don't know if they are stress-related, CLIPPERS-related or prednisolone-related. In both cases I do get some sleep and am not incapcitated like Al Pacino but the regularity of the sleep disturbance is strange.
