If you think the infection my be in or come from your throat then eat fresh pineapple. There is an emzyme in pineapple which kills most throat bugs. My dd used to get throat and ear infections about 4 times a year (really badly infact hospital twice once it caused septacemia). Since we found out about the pineapple she gets rid of them within a few days - and very rarely needs antibiotics now. You need to suck on the chunks to get most of the juice out before chewing them. After abou 1/2 the whole pineapple you can actually feal it attack your throat. I couldn't believe how well it worked when I tried it out.
Also use sea bands to combat the nausea- they work for me
PS- I'm not some non presecription drug lover - I am infact a chemist - but this really does work and is now my "drug" of choice for throat and head colds.
Hope something works for you
