Need some advice

Idk if this is right place sorry if I’m mucking up the sub

Possible breathalyzer test in 10 hours. Just cracked my 7th beer which will be the last consumed tonight. Male 190 lbs gonna take a long bike ride and sweat like your mom at the donut factory working OT before I go to my outpatient rehab. Am I fucked, possibly fucked, or fretting about nothing?
