My suggestion is to keep a good attitude to face it. It is more important to take enough medicine. What is enough medicine? That is to say, cold granules should be taken regularly in sufficient amount according to the instructions without interruption. Be sure to take some anti-inflammatory drugs, because most colds are accompanied by inflammation, and if inflammation occurs, it will be very uncomfortable (believe me, your cough will be particularly obvious in the whole examination room, so you have no intention of taking the exam). If there is no inflammation, it is necessary to take some drugs with poor effect, such as cefradine and amoxicillin, a few days before the exam to prevent it. Never take it for a long time. If there are symptoms of inflammation, such as dry throat, cough, ear inflammation, etc. When using it for the first time, be sure to take it at the maximum dose and drink plenty of water. The normal dosage can be restored when taking it for the second or third time, and the maximum curative effect can be exerted. Remember to take medicine 2 hours after meals, which will do less harm to the intestines.
