racegirl one rule of thumb in this day and age is to never carry a full bottle of potent pain medication with you,only take what you will need until you get home to get more.remember the amount that you take could very possible kill a teenager or someone that is not opiate tolerant.forget about the oil change place and dont let this happen again.please dont take this the wrong way but you as a pain patient have an obligation to protect your meds and plus you dont want to run out early im sure.chalk it up to a hard lessen learned.good luck-spark
