It's like the commercial, "Once you pop you can't stop."  Once you pop a pill, you can't stop.  They have you hooked and they know it.  Like a drug dealer, they are so happy they have won another loyal customer.  Not loyal because you want to be, but loyal because your body is now completely dependent on them and their legal prescription "drugs."
