Expert answer:
As a doctor, I am obliged to say that your conduct is dangerous and inappropriate, but in a way it is logical. But it will not always be right, it can often confuse symptoms, take too much medicine or take less medicine, may mask the symptoms of more dangerous diseases, create bacterial resistance due to inadvertent use of antibiotics and so on. When things are simple their logic works, but when things complicate their logic they put you in an even worse situation.
