I have been taking Oxycontin & Dilaudid/Hydromorphone for approx 9 mths due to extensive painful surgeries and they have been prescribed by a pain management Dr. I am ready to go to school to obtain my CDL & then go to work at the same company my husband works but i will need to take a urine test when i start school & then 3 weeks later another urine test one when i go for the new job. What can i use?
