I think rather than remembering, you have to make it a default part of your routine so that you won't need to remember, you will just do it on auto pilot. It won't take long until it becomes just a thing that you do without needing to think about it, but to get there you do need to be strict with yourself, set alarms & don't let yourself get away with excuses.
I'm sure when you were little your mum would have to remind you to wash your hands after going to the loo. But there's no way you would think now I must "remember" to wash my hand, you just do without even thinking because that's how you do it.
You just need to think I test, I inject, I eat. They come as a package. Make a resolution, Be strict for a little while, set reminders in your phone, put post it notes on your fridge, tell people around you to help remind you & soon you'll just be doing it automatically.
