Is any of this happening?
Be seen today
Seek prompt medical advice if you are becoming confused, falling, or struggling to stay awake during meals, conversations, or other normal activities.
Do not drive if you feel likely to fall asleep.
These symptoms may have causes other than a sleep disorder and need urgent assessment.

Does any of this apply?
Book an appointment
Arrange a routine appointment if poor sleep lasts for several weeks, affects daytime function, or causes repeated unplanned sleep episodes.
Assessment is also appropriate for loud snoring with gasping, repeated breathing pauses, uncomfortable leg sensations, or dream-enacting behaviors.
Every sign above is quoted from the sofidex article on Sleep disorders in older adults. If you are not sure, err upward — it is always reasonable to be checked.
