HEADACHE.--This is a symptom of great importance. If it occurs [84] frequently, without apparent cause, the physician should be consulted at once, as it may indicate a diseased condition of the kidneys, and necessitate immediate treatment. Headaches may, of course, be caused in many ways and most frequently they do not have any serious significance, but they must always be brought to the attention of the physician. As a rule they are caused by errors of diet,--too much sugar, candy, for instance, late and indigestible suppers, indiscriminate eating of rich edibles, etc.,--or they may be products of nervous excitement (too little rest), as shopping expeditions, strenuous social engagements, late hours, etc. ACIDITY OF THE STOMACH, AND SO-CALLED HEARTBURN.--These are sometimes in the early months of pregnancy annoying troubles. The following simple means will relieve temporarily: A half-teaspoonful of bicarbonate of soda or baking soda in a glass of water or Vichy water; or a half teaspoonful of aromatic spirits of ammonia in Vichy, or plain water; or a tablespoonful of pure glycerine. The best remedy is one tablespoonful of Philip's Milk of Magnesia taken every night for some time just before retiring. Heartburn is the result of eating improper food, or a failure to digest the food taken. Starchy foods should be avoided. Meats and fats should be taken sparingly. Avoid also the et ceteras of the table, as pickles, sauces, relishes, gravies, mustard, vinegar, etc. Good results follow dry meals,--meals taken without liquids of any kind. Live on a simple, easily digested, properly cooked diet. Chew the food thoroughly, take plenty of time and be cheerful.
