Just came back from COSTCO and once again amazed by the cupidity & stupidity of congress. Ten years ago Quinine Sulfate cost $.40 , then congress decided that a drug in use for 500 years was not properly tested. The result? ONE company was made the only one to make quinine sulfate for sale in the USA. The price went from $40 per 100 to over $550.72 per 90. This drug is the only proven, consistently effective treatment for severe muscle cramps. Hope you don’t get Malaria or you will be in a financial mess.
