Is this the correct way to write this sentence? I thought about saying, "I knew this would interest you as much as it did myself", but wasn't sure if 'me' or 'myself' would be correct.
Dictionaries provide answers to this type of question.
According to Dictionary.com, Art. "myself",
the pronoun "myself"
1. gives more intensity to "me"
2. and is used
in place of I or me after as, than, or but [my bold]
The second aspect suggests that while "me" is not wrong, "myself" seems to be more common.
I don't know though if there is a reason why "myself" is preferred over "me".
