Personally I think you failed and they like you enough to bend the rules and give you a second chance. You got some really good advice, follow it. You should start taking the maximum guideline amount for metamucil immediately and if you can get some good cardio workouts going do it. Make sure you stop working out 2-3 days prior to your next test. Also at the same time you stop working out, begin taking a creatine supplement. Its covered in the dillution sticky. The day of the test drink gatorade instead of water and skip the aspirin. Do not drink excess liquor it wont help clean your system. Do not buy any GNC products except for the creatine. Definitely invest in some home tests to see how you are doing and practice dillution prior to the test. Have both synthetic urine and dillution ready to go since you may be observed. Good Luck.
