"Academics claim that an excessive dosage of sleeping pills may lead to headache or dizziness." (From Ivy magazaine)
Is this sentence correct? According to many dictionaries, the word "headache" is a countable noun, but it stands alone (with no article or s) here. Is it used wrongly?
"Gina informed me of the change of venue for our family reunion." (From Ivy magazaine)
I have the same question with a different sentence here. The word "venue" is countable, but it stands alone here. Is it correct?
Both sentences are correct and natural. Both headache and venue can be countable or uncountable.
