I would highly suggest trying an outpatient addiction program. If you are able to work and don't call in sick, it sounds like you can maintain your job and attempt intervention with an outpatient program. If this is not succesful for you, an inpatient program may be more appropriate. Use your local Yellow Pages to see what programs are out there. Good luck! Addiction is hard to quit, but once you do, the weight of the world will be taken off your shoulders.
