"I threw up a couple times before the game and that made me feel better," said Johnson, a former Cub making his Wrigley Field return. "And the IV got some fluids in me, but I was a little woozy my first two at-bats -- [a comebacker and a strikeout].
"But I started to feel better as the game went on. Then I had a horrible headache overnight and figured if it didn't go away, today wasn't going to be pretty. But it went away, and I finally had a little bit to eat this morning and I'm feeling a lot better."
Johnson said his wife and child were released from the hospital on Thursday morning and flew home.
