Sorry cinnamon, I think I read your post in the wrong way! I don't think you are weird at all.
I have to use advice or advise in a sentence in my head. For example, I advised someone how to do something is similar to I practised doing something. Or if I went to someone for some advice, that is similar to going to a sport practice... I think I usually work out which is the verb and then know the other is the noun. Somehow I know that "I advice that..." sounds wrong if that makes sense, but "I advise that..." sounds right.
