Told I can’t take adderall as an FA

hey all, so i just recieved my CJO from an airline and i was told in depth that i can’t take adderall for my ADHD as it is prohibited and i will be fired if i continue to take it. has anybody experienced this? im nervous about continuing my medication and getting pulled for a random drug test and it coming up positive and losing my job. any advice to help navigate this would be greatly appreciated!
