Refeeding on lemon juice after a long water fast

Refeeding with lemon juice?

Hello all, I am currently on day 12 of a 43 day water fast. This is my second 30+ day water fast. Last time, which was a couple of years ago, I did not do the refeeding properly and due to irregular eating and work habits, gained all the weight back. Now I am determined to do it right and eat right (hopefully) for the rest of my life.
So my question is, after my 43 day water fast, how many days should I be on a liquid diet as part of the refeeding process? Also, I have read on the forums, that I need to start with a juice like Watermelon or orange. Can I do this with lemon juic instead? The reason is, I hate any kind of sweet things be it fruit or desserts. Since orange is a citrus fruit and it can be used for feeding, can is substitute it with lemon juice with some salt?
Another question is, I am planning to do a Water Fast every Monday and alternate day fasting from here on, as well as a 7 - 10 day Water Fast every 2 - 3 months. Will this be too much fasting?
Oh & btw, I am a healthy 35 yr old female. Thanks in advance for replies/advise/suggestions. Tweet
