Whether it belongs to Chinese patent medicine or western medicine, all western medicines are basically eaten about 30 minutes after meals. It's best not to hurt your stomach. Traditional Chinese medicine and Chinese patent medicine can be eaten on an empty stomach in the morning and after meals at night. In view of your schedule and the western medicine you may take, you can get up at 7 o'clock and buy breakfast halfway. Take an empty bottle at school and fill it with boiling water that is not very hot (if it is too hot, the bottle will break). If you use cups, don't use mineral water instead. When you get to school, if you still have time for class, you can take the medicine before class. If you have just finished eating, you can eat between classes. Basically, there is no time limit for about 30 minutes. You don't have to drink a lot of water.
