good questions! i too wondered about all that yesterday but decided to go with the extra virgin olive oil i had and 2 graperfruits. and yes when mixed with the grapefruit it goes down quite easy. i think the apprehension for me was a lot worse then the real thing.
i don't know why i din't keep it down, maybe parasites, i sure passed some, or the fact that i had to get up and go bm every 5 minutes, but next time i will be taking some sort of sleeping aid.
