Does he die at the end??

My friends and I had a good time watching this movie. For a low budget independent, it's pretty well done and keeps you entertained throughout. Some really classic moments in Break. Obviously it was an intentional thing by the filmmaker but it drove me a little crazy that you don't know whether or not the woman poisons Frank at the end or not. The implication is there, but it leaves you hanging. Curious to hear other thoughts.
