You're doing everything you can already. Keep taking co-codamol + ibuprofen (try and eat something before the ibuprofen-that might be what made you sick).
You could get a throat spray as mentioned. If youve got any soluble aspirin (300mg) dissolve in water and gargle with it. If you decide to swallow it (no jokes please!!!) then skip a dose of ibuprofen (co-codamol is fine, ibuprofen OR aspirin).
Hope its better soon
