bro many people face different situations, for example, my father suffers insomnia, and usually take a very strong sleeping pill before fajr, this pill actually states that you must have a set amount of water in periods through out the day, now iv asked them, is it possible to not drink? and they said it is impossible, the thirst is literally unbearable, now they either take the pill, drink and make up their fast, or not take it, have a sleepless night, which means that they're fatigued throughout the day, and their job requires concentration thus not taking the pill actually puts their life in danger whilst working.
