Can't imagine why it would be an issue - it is not an NSAID and has no impact on blood, etc. Some docs (like mine) give Tylenol in the morning immediately pre-op to start the pain-killing process. I wouldn't worry about taking a couple of T's if it was me. Hope U R ok.
For last year's words belong to last year's language.
And next year's words await another voice.
And to make an end is to make a beginning.
