If you are referring to the Medicine Puzzle on page 10, the solution can be found by clicking on the small question mark on the bottom right corner of the page. Clicking it once gives a hint, and clicking it a second time provides the answer. (On many other pages, this small question mark is also the way to find hints and answers). Hope this helps, if not just let us know. I very rarely check this forum anymore, so you are also welcome to ask questions by emailing me at firstname.lastname@example.org. Thanks!
