Yes, I was shocked!
I am/was a regular Motrin user, no problems.
I remember I hurt my back and had to take my kids to the movies, so I popped an Aleve for the first time. Within an hour, as I was driving to the movies I got SOOOOOOO tired. I had to tell my kids that I could not go. I felt that way all day and once it wore off I was totally fine.
My best friend had the exact same issue with it.
I was sort of surprised by this as I used to take Naprosyn (prescription) when I was a teen and it never did that to me. I think it is the same drug or very similar.
I also have a coworker who feels very odd when taking Motrin.
