Ok, wait, your wife gives him something that is prescribed in bulk? (I have been given an entire years supply of it at once although it is not recommended to be taken every day for that long, the Govt don't care about us).....I'm not a rocket scientist or a physician, but I have taken Doxy on multiple occasions for very long periods of time to prevent malaria. Could you please tell me what type of bacterial infection he has? Because I would think that if he is taking Doxy on the reg it must be horrible. Or is it Acne?
