Regarding the woman who overdosed on calcium: Your next step should be to contact a lawyer and sue that antacid company. It's clearly their fault you didn't read the warning label. Then sue the doctors for not asking you if you were taking any OTC medications. They should have known you were. Next, sue the government at the local state and federal levels for not developing an antidote or providing enough calcium rehab centers in the area. Sue the police department. If they can carry around Narcan for opium addicts, they should have something for calcium ODs.
