Sounds like everyone experiences different side effects mostly revolving around a bad case of the flu. I didn't get the metallic taste although, I know that is a side effect of many drugs.
You should start feeling better pretty soon. For me it was pretty much like I woke up one morning and thought, crap I don't actually eel that bad today and it just kept getting better.
Sorry, not much advice other than to say hang in there your over the worst of it.
