Others have suggested mixing with cordial to mask the taste. Because the taste is so bitter, tasting something more bitter beforehand would make it seem less bitter in comparison. It's only a small amount of water so you could just mix with cordial, slam it down then chase with something strong tasting.
The CO tablets with ibuprofen don't contain any codeine. The ones with codeine have 500mg paracetamol per tablet.
