Adding medication requires all fields be populated

[schmitzkr]

When I try to add a medication to a new medication plan, I need to populate all the fields, and there is no way to know what needs to be populated it took a few tries to get something added there. Letting me leave a blank and having that equal 0 when I submit the form would be a time saver. It might also be useful to add a unit to the time of day requirements? for example "Morning" I can populate with '1', but not '200mg' I guess I could name the medication 'Med1 200mg' and then populate "Morning" with '1'. If this is best practice, then it might be helpful to have some sort of tip in this screen. Thanks for your wonderful work on this app! 😀
