Best Of Times, Worst Of Times, etc.
Still NOT on vacation.

From some NIH website--
People prone to forming calcium oxalate stones may be asked by their doctor to cut back on certain foods if their urine contains an excess of oxalate:
beets
chocolate
coffee
cola
nuts
rhubarb
spinach
strawberries
tea
wheat bran
People should not give up or avoid eating these foods without talking to their doctor first. In most cases, these foods can be eaten in limited amounts.
