"I felt pretty groggy on the front nine just from the drugs that I had in my system, then kind of flushed that out on the back nine. The vertigo came back a little bit on the 13th tee box, and then felt nauseous all day. I started shaking on [the 16th] tee box and then just tried to get it in, really. Just wanted to get it in."
