I’m so sick of my wife forgetting to do things (like take the medication that if she misses a dose it ruins her entire next day and sets off a ripple of migraines that can last a week) that I’ve just started stealing her phone to put in reminders.
If she has trouble remembering if she's taken the meds, I highly recommend TimerCaps. They are a pill bottle lid that tells you how long it's been since the bottle was opened.
We have several at my house-- I can check and see if my partner has drugged the dog or if I've taken my ADHD meds. My partner can also see if I've taken my meds.
