Rehab was originally formed by vocalists Danny "Boone" Alexander and Jason "Brooks" Buford, with producer Denny "Steaknife" Campbell.

Alexander and Buford were recovering alcoholics and drug addicts, and while it is a common misconception they met at a rehab facility, the trio did not meet within rehabilitation.

Cee-Lo & Bigg Gipp of Goodie Mob, Mandy Lauderdale and Cody ChesnuTT were the guests on the album, which spawned the Top 15 modern rock hit "It Don't Matter", and "Sittin' At A Bar".

For reasons not publicly clarified, Buford left the band, and released 26 unreleased Rehab songs on his website towards the end of his tenure.

Boone also modified the track list of the pressed version, removing certain songs and adding new ones, in light of Buford's departure.

After two years on the road supporting the Vans Warped Tour and playing with bands such as Linkin Park, the group went on an indefinite hiatus.

Buford did not return to the group, however, later appeared as host of 2005's Trailer Fabulous on MTV and recorded a single for the show's theme, before joining the short-lived project The Audio Club with Tommy Hendriksen.

Gullible's Travels was released on February 21, 2012 through AVJ Records (a subsidiary label of Average Joe's Entertainment) owned by former Rehab producer and manager Shannon Houchins and country music artist Colt Ford.

Before the break, the band recorded a full album titled Million Dollar Mugshot, which Average Joes Entertainment did not release until 2017.
