Jayson Williams - Free to Booze Before Prison

Former NBA star Jayson Williams will have four days to drown his sorrows before heading to prison next week ... because the alcohol monitoring bracelet is coming off.

Jayson's lawyer, Linda Kenny-Baden, tells TMZ the SCRAM bracelet he was ordered to wear after his DUI bust last month will come off on Friday.

But Jayson's bracelet isn't being 86'd for a good reason. He's being sentenced to prison on Tuesday over the death of his limo driver -- and the bracelet has to come off before he goes to the pokey.

It must Absolut-ly suck to be Jayson.
