Rat poison = Warfarin. I take 10mg a day and I'm no rat. It's a blood thinner used to keep my blood from clotting my artificial heart valve. I used to take it at 5 PM sharp everyday. To remind me, I had the alarm on my phone go off. I even recorded the personalized alarm: "Hey Swiggy! It's Time For Your Rat Poison." The guys at the club always got a laugh out of that.
