I last had cholesterol and related tests done last after I had been vaping exclusively for about 6 months. Due to a work deadline, I was up all night and vaping heavily all night before going in first thing in the morning for the tests. All of my results, including the cholesterol results, were well within the normal range.
Can't eat or drink anything but water before a lipod test. So you was up all night and never ate or drank anything but water for 10-12 hrs, bet that was tuff to do. The only way I can go that long without is while sleeping.
