"As our headline explains, it's recommended that you pick up a bottle of Watson's Pure Distilled Water as soon as you've finished your workout."
Q: I want to put "with" before "your workout", could you tell me how to modify the other parts of the sentence so as to be grammatically and semantically correct, at the same time, keeping the same meaning?

"Mary speaks quite highly of Thomas' book."
Q: Can I replace " highly" with " positively"? If not, why? Any difference between the two? Is that it should be "...positively about Thomas' book."?

1. You can use either "finished" or "finished with" and have the same meaning. You can also delete "'ve". ....as soon as you finish your workout.

2. To speak highly of something is to speak favorably with admiration and respect. Positively does not carry as great a degree of approval as highly.
