Dear Rabbi Simon
WRT to the upcoming Fast (of Esther): I intend to fast, however I am prone to migraine headaches. These can get progressively worse on a fast day (but I will get through it). What are the rules around taking some pills?
If you can swallow a pill without water there is no problem at all in taking it. If the discomfort is intense you may take it with a small amount of water eg an ounce or two. If this is insufficient let me know and we can discuss other options. (The Fast of Esther is less severe than other fasts, so if you need to break your fast, you may do so. However strictly speaking you may need to make it up on another day.)
