Do you have that kind of experience with acetaminophen?
Show me where any neurologist says two x 500 mg once per day has caused headaches in even one patient.
When they talk about chronic use, they are talking about people that take the maximum, or near-maximum, dose every day. That is 2 x 500 mg every four hours! That I will not do.
Dosage is a major factor in the body's response to most drugs.
