"Once I vomited on the ride, and then swallowed that one back down," the 31-year-old said.
"I had a couple or three good moments on that run... The run was really hard for me this time, because normally when you're racing at the front, you just don't care.
"Your feet hurt, you feel sick, you feel nauseous, but you don't care because you're in the race, but to be back where I was, it was quite a different experience."
Despite his misfortune in the unforgiving Hawaiian climate, Currie has kept the door open to a return to Kona in the future.
"I'm probably not the obsessive kind of type, but I feel pretty hard done by with this race," he said.
"I don't normally give up until I've completed everything to I feel the best of my ability, so I don't think I'll give up on this one until I pull off a race that potentially might not be a win, but I get through the race, and I race how I want to race, which I believe could take me on that podium."
