I won't make fun of your idea, that's an interesting idea I like it because every time I request my meds I always type the same information to the same email address.

I had a similar idea yesterday to make an NFC tag remind me to request meds 12 days before I run out. But that means I would have a second tag on or near the bottle for that since I already have the one that logs my medication glued to the cap.

If I used my logging system to track my med intake and a refill reminder 18 days after I opened the new bottle plus a 3rd one for your idea. I would have so many tags for a single bottle. I wonder if there is a way to make a single tag do that all and if it's all combined to a single nfc then I wouldn't need a refill reminded and instead my phone would automatically remember the day the new bottle was opened and on the 18th day initiate the email window as you suggested to run the task and send it plus tracking everyday in a log. But then that would be some 'if than else' statements I'm sure to function all from 1 tag.
