The aviator in question was 23 at the time, he bombed on into his local AME for a first class, he had a Horizon interview the next week. He had glucose in his urine and was deferred. His Stepfather was supportive and put him on a regional form Buffalo to Peoria. The young man rolled out of bed at 08:30 for his 09:00 apt, had a bowl of Captain Crunch and arrived at the office and he had glucose in his pee. I set him out for with three bottles of water, then another three, and told him to flush and after a bunch of 12 oz bottles of water, he was again positive. I asked him, what was he eating? He replied, "Almond Joy". I gave him three more bottles and we tried again. Still positive. I asked him if he'd eaten anything else. He replied, "Clark Bar". After three more bottles and telling him "I was concerned if he was Smart enough to work on a flight deck", At 1:00PM I got a negative and Called OKC. And how after how many tries did you succeed in getting a negative urine?"
"Three, sir"
"Issue him!".
"Yessir".
