The Scream star, who spent much of January (11) in rehab in a bid to kick his alcohol addiction, has now admitted he wouldn't let doctors prescribe him any pain pills as he doesn't want anything to interfere with his quest to quit drinking.
He has also told fans he was on the way to the airport at the time of the crash to fly to Las Vegas to attend a restaurant opening - but has now cancelled the trip.
In a series of posts on his Twitter.com page, he writes, "I was on my way to catch a plane to Vegas to help my buddy Stevie D open his restaurant The Sugar Factory. So sad I'm going to miss it but glad to be alive for a rain check. Refused all pain medication - may the record state - still sober! It was a miracle the woman I hit was uninjured - thank God!"
Arquette has also admitted he wasn't wearing a seatbelt at the time of the incident, and urged other road users to always buckle up. He adds, "Remember to wear your seatbelt - wish I was."
