I can attest to feeling nausea on day 2 whenever I've done a 3 day water fast. I never go beyond 3 days; I don't have the will to do it and I currently don't have a reason to develop it. You really don't need to fast that much to get benefits from it. Seeing as it is your first fast you might benefit more from doing one day weekly. That's what I did for a while-I slow carb, so when I needed to cleanse a lot of junk from my system I ate normally for six days and fasted one for a month.
If it's not critical, "I'm going to do this or I'm going to die," then you're better off planning and sticking with something less intensive that's easier to maintain. Hell, I've done 2 and 3-day fasts before and it's usually difficult for me to get past 1.
If you eat meat switch to organic, get rid of any junk food or anything that doesn't have a lot of nutritional benefits for the body, maybe add some supplements, and fast once or twice a week. Add some green tea to your non-fast days to help cleanse the liver, 4-6 cups should be fine; you can drink up to 10 safely. That's the sort of thing I'd recommend going with. It's possible you'll get better results, too, as it won't shock the body so much. That's key-you do not want to go too far beyond the body's comfort zone when you don't have to. Stretch, don't break, if you get my meaning.
