I've been taking xyrem for 2 years now (sleep problems). I'm switching jobs and I'm concerned that I'll now test positive for what is for me is a legal medication. If I were to stop taking this medication for awhile, how will it remain in my system and still test positive? I know that I can simply report this as a legal medication but after speaking to several people it was suggested I not chance it because of the new position. Again, how long does it remain in the system and am I realistic to believe I can simply not take it for a short period of time and not have it show up?
