I did this before using a password manager. I found that it does work but it's still a pain.

For example, what do you do when you're forced to change a password? You need to remember that this website doesn't follow the rule. There's also the case of password being used by several websites with different names or urls, you need to remember which is the base one.

Also it's really convenient to store other things than passwords in the password maanger. Like some notes, your customer number, which email you signed up with, some PIN they give you...
