In 2003, he entered a rehabilitation center near San Diego for a 45-day program. His newfound sobriety was almost immediately tested. Before entering rehab, he had left money for his roommate to keep the house and pay bills. The roommate instead used it for drugs and gambling; when Garrigus returned the night before he was to play in a sectional qualifier for the U.S. Open, he found the locks changed and the electricity disconnected. The roommate had left town to avoid gambling debts, leaving behind a substantial quantity of marijuana and a note reading, "Hope rehab was great. Have fun." As Garrigus would say,"I stood there for a minute, and then I grabbed the weed and threw it in the garbage. Then I took the refrigerator and threw it out with the chicken, everything. I called the electric company to get them to turn on the power. When I wake up the next morning, I didn't realize until I get to the golf course that my roommate had been using my putter. So I race back to the house at 140 miles per hour, get my putter, race back just in time for my tee time. I have no warm-up, no caddie, and my clubs are on a pull cart. I shoot 70 and miss by two shots. I told myself that wasn't too bad after 45 days without hitting a ball. I knew then I was going to be OK."
