I'm suprised by the negative reviews but to each their own I guess. I thought it was a sweet movie I saw it at ifc center in a very small theatre and it was nice ,other people seem to enjoy it too. It's not perfect ,I didn't love the scene when Charlie and Francesca first meet ,it was a bit ott but overall it was enjoyable. To people in real life with narcolepsy/ cataplexy I can't imagine living with this illness and I don't think they made your illness a joke. I really felt for his character's situation it's not all laughs.
FYI: to earlier comments that cataplexy doesn't cause narcolepsy,and that its a symptom. That was a mistake in the description that was corrected. In the movie they state that he has narcolepsy with cataplexy so it makes it clear that it is a symptom that not everyone with narcolepsy has and that it's not necessarily the same for everyone with the illness.
