Like clockwork…

Rita Wilson doesn't know if chloroquine helped her in her Covid-19 fight. She only knows how it made her feel on her road to recovery.

In short? Not good.

"I don't know if the drug worked or if it was just time for the fever to break," Wilson said on Tuesday, noting the "extreme side effects" she experienced.

Wilson, who came down with Covid-19 while in Australia with husband Tom Hanks, told CBS This Morning that the medication left her "completely nauseous" and suffering from vertigo. She was given the drug about Day 9 of her illness, she said.
