Turned out I was quite sick for 10 days - with fever and vomiting, leaving me feeling half dead. I toughed out 3 days of the fever in my hotel before realising i was getting too weak to go downstairs to buy water and ended up spending a week in the hospital on a drip (and some occasional oxygen). The major diseases came back negative - malaria, typhoid, dengue fever. The doctors say i have bronchitis, but they think the bronchitis is a secondary infection rather than the main cause of my fever.
Anyway - I gave up on my adventuring for a while and have come back to adelaide to recover at my parents place.
It's a cruel world out there for a nice guy like me.
