We take the HCQ in tonic water which has quinine.What tonic water do you drink? Look into it - some name brands don't have any quinine in them, they just add a bit of bittering to mimic the taste.
FDA regs limit quinine in tonic water to 83 ppm, which is about 40 mg in a half-liter bottle. So you'd need to drink about 20 of those bottles to hit malaria-level quinine dosages, and that's assuming your manufacturer is hitting the max amount allowed, and not cheaping out and only adding half or even less.
