Letrozole for the next 10years..

When it is something you have to remember each day - AIs or other medication - you just do.  This is a matter of human survival so you put them where you see them, perhaps by the kettle, perhaps by the bed etc.
You are not the only person needing to take medications daily or several times a day for a variety of illnesses but we all make it work.
If needs be put a reminder in your phone.

I make my own pack - a 7 day, 2 compartment per day box from the chemist, fill it up once a week. Mind you, I have more than one medication and a few supplements (all recommended by doctors) so it’s just much easier to know what I have taken. If it’s only one pill, take it first thing when you get up or last thing at night. Some find it makes a slight difference re side effects, so the usual trial and error applies. I’ll be stopping taking the little pink pill in seven months (yes, I’m counting down) and imagine that will be strange too! 

I take another pill at the same time. It is built into my daily routine. You could set a reminder on your phone or set an alarm clock or even a postit note on your kettle or fridge. I guess @Fernweh, it's a matter of working out what will trigger your memory. 

I have a Webster pack from the chemist  ( as I have to take other pills in the morning) which has am and pm
I take the AI ( was Letrazole , have moved to Exemastene) after dinner every night.
It’s just something I do every day.
I did in the beginning ask my hubby yo remind me but it’s so ingrained now (18 months on) I don’t need a reminder.
