Yeah, the taste matters if you are going to eat it for 2 weeks :). You will probably still hate it after the first week, but it is just one week of misery instead of two. I did some fasting in the past, leaving only water, tea (no sugar) and peeled apples in my diet. Had to do it for 2 weeks, but only made it to the 11th day. The issue with that one was the low calories, which doesn't correspond well with active work (I did not plan properly to take the second week off). Nevertheless, it helped solve the colitis issue, with which I'd been struggling for a few months. An interesting observation was that up to say day 4 or 5 you actually have more energy and sleep less. But after that it was a bit of a struggle to retain the same levels of energy and be productive at work.
