Overdose - need some help asap please

[frankz81]

hey all,
swim has foolishly had too many codeine tablets as he was in withdrawl and was desperate to get out of it,
he ingested 12 x 15mg/500paracetemol and 2 x 10mg/500 para making it
7000mg of paracetemol, and 200mg codeine although thats not wats bothering him even tho it has caused hot and weird sensations in his head, its the 7g's of paracetemol that bothers him...
for someone in tip top healthy condition, can 7000mg pass thru him without causing damage? here is australia they say 4000mg is safe in 24hrs but surely there must be room for error,i mean 4000mg is safe therefore 500mg on top wouldnt make much diff right as in there should be a lil grace...
any1? i could use some advice on worst case and best case scenario on this, and also a realistic scenario,
thanks
