wake up and smell the coffee

I made this puzzle following Scojo's prompt to use zipper lines and anti quadruples.
- Normal sudoku rules apply.
- On zipper lines, pairs of digits equidistant from the center of the line have the same sum. For lines of odd length, that sum is the central digit on the line.
- Digits in a red circle may not appear in any of the four cells touching that circle.

Very tricky, but there is some really nice logic in there.

Very nice! A great challenge, although I am sure I did not find every step of the intended path, so it might have been a bit easier. Thanks
