I want to know what medications shows meth in it. I m seeing a pain manager and I get tested before every refill. Ive been sick for almost two weeks and have been taking all kinds of cold and flue meds. I can t shake this flue. I had a conversation with a coworker and she notices that I use a vicks inhaler all the time. She told me that if I keep using the vick inhaler and take any cold meds that keeps me up. I will test positive for meth, narco, even oxcidcodone . Is this true? I just started seeing this doctor cause I had back surgery two months ago.
