I have fasted before and it helped greatly with my depression. I have a bit of bipolar going on, however mine is mostly induced to Sugar highs and lows from compulsive eating. After about five days on water, it was as if the heavens opened. I was calm, clear, at peace. My mind felt so tranquil. I was able to read for the first time in years. My creative streak came back. And, well, I just felt fabulous. I do think that Water Fasting is a valuable tool for emotional issues. The first few days can be grueling - I felt like I was having an exorcism - Being in a supportive environment helped. Often those of us with biochemical imbalances self medicate with food. It is hard to get through that crucial period without support of determination like steel. Good luck!
