I just finished my 5 day water fast. I'm now gradually feeding myself with fruits and fruit juices. I expected that this fast will improve my ulcer and worsen my infectious prostatitis (they say fasting weakens immune system). However things didn't go exactly like that - fasting improved my infectious prostatitis (almost no pains now),and maybe improved my uninflammatory prostatitis too (yes, I have two types of prostatitis). However for the first 3-4 days my stomach and oesophagus began to improve, but on the 5-th day they started to hurt a lot. I guess that's because of the toxins one excretes during fasting - they irritate the inflamed place. At the end my ulcer is much better too so I'm happy. The 5 day fast didn't have any influence on my chronic fatigue - it's still the same- not better, not worse. I stopped the fast because of the stomach and oesophageal pains, and feeling very nauseus on the 5-th day. If I'm able to heal my ulcers through diet, I will attempt another , longer fast. Say 10, 21 or why not 40 days (like Jesus Christ). And I hope to cure at least my infectious prostatitis with it.
