I try to throw the bottle to the bathroom entrance, and once I'm done in the way of the front door to make it a physical inconvenience to forget it (then hopefully goes on the shopping list)
This is my universal system. It doesn’t even need to directly correlate with the reminder, since most of the time I just need to be reminded that I need to remember something.
For example, I’ll leave a chair in the middle of the kitchen so I remember to do something when I get home. The second I see it I remember whatever it is I need to do. I’ll leave it there until it annoys me into doing what it was I needed to do. Very effective for my ADD/OCD combo.
