Being trilingual

I recently completed the Japanese program at my school and started the Chinese one.  I have been forgetting my Japanese at an alarming rate.  Is it possible to learn more than one foreign language in addition to your own or should I give up?

notice how all of the languages you mentioned are closely related to one another in at least one respect?  how the fuck does that relate to the OP?  don't even say kanji because kanji in chinese and japanese are two completely different things, keep your useless comments to yourself
