Question about refeeding juice...

Hello again everybody!I have a question for all of you water fasters. I read so many posts and resources stating that when coming out of a water fast,you need to do 1 day of juice for 4 days of water fasting, and then raw fruits.I understand all that, but I don't have a hi tech type juicer. Is boxed juice allright, or is that a lame question? Do I need to have actual fresh juice? Can I maybe only have orange, tangerine and grape fruit juice, since I can squeeze those?Thanks all!
