Wow, 12 days on water - congratulations!!! And, if I'm not mistaken, 20 lbs down, which is awesome! Thanks for your posts, I read all of them just now; they were a great way to mentally prepare me for my water fast which I'm starting tomorrow.
Last year I managed to fast for 3 days (on water), but broke it on day 4 after I felt soo weak I could hardly get out of bed and go to work. I'm really worried about the side-effects (dizziness, nausea, weakness, insomnia, headaches), last time I experienced it all.
My weight right now is 147 lbs, I'm hoping to shed 20 in the next month or so. I'm not sure how long I'll stay on the fast, but I sure hope that I can keep it up longer this time.
Stay strong and keep me posted on your progress!!!
