Unless it's been changed, it's 3 days of chemo and then an 18 day break. He must be having horrible side effects to be kept in hospital over a week. He probably has an enlarged liver from all the booze and it's making it much more difficult for his liver to process all the chemo being thrown at it. He's screwed,I thought it was five days of chemo. Regardless, I agree with your assessment.
"Ford is expected to start to undergo three days of chemotherapy in hospital in the next 48 hours. After 18 days, the chemotherapy cycle will be repeated and doctors will assess the response and next steps."
