The most common symptoms you will experience are excessive sleepiness and daytime sleep attacks.

Cataplexy (sudden loss of muscular control) triggered by an emotion e.g. anger or excitement is also a common symptom. The onset of this symptom may be delayed, sometimes by a couple of years.

Other common symptoms include: -

Sleep paralysis (inability to move for a minute or two at the beginning or end of sleep)
Hallucinations (dramatic, dream-like experiences) immediately before falling asleep
Disturbed night- time sleep, with frequent waking periods, marked by a fast heart rate, agitation and a craving for sweet things.
There may also be abnormal behaviours e.g. sleep walking
Short periods of trance-like behaviour in which routine activities are continued automatically

Sleepiness may also lead to blurring of vision, double vision and problems with memory and concentration.
