FWIW nobody's been a native Latin speaker for a thousand-plus years. You're in the same boat as everybody else! ;-)

True, but the problem is that my language (Italian) only uses "es." for "e.g." and doesn't have an equivalent acronym for "i.e." (we usually use other complete words that roughly translate to "therefore"), so it's easy for me to mix them up since I can't easily map them.
