I have two medication times - the first lot with breakfast, and the second lot at bed time. I find that they are two things that happen in the same way every day and around the same time every day. This has gone on for years, but it's such a normal part of my routine now that I just never, ever forget. I keep my morning tablets where I have breakfast, and my night tablets are with my toothbrush. Fortunately I don't currently have any that are taken morning or night.

The alarm on the phone is a good idea if you always have it with you, but it doesn't take long before it becomes habit if you build into a part of your day that doesn't change much at all.
