From experiences of friends in the past I decided to abstain from all 'plus' and 'forte' over the counters from when I had my full interview. Poppyseeds were also on my 'avoid' list!
Friend had a false positive come back on their urine - it was sent away for the further testing - came back as 'inconclusive'. Then they had to do a 2nd urine test about a week later! $$$$
You'll be fine - but if you were like me last week any little thing that seemed as tho it could delay your possible starting in any way just became the thing of nightmares.
Anyone on the board starting on the 13August? I found out yesterday
