White Shark, no I haven't done any liver flushes. I will look into this and give it a go.
I haven't eat gluten in a couple of years now as I am pretty sure I am intolerant to it anyway. I'd say I have a reasonably good balanced diet and have tried eliminating various possible food causes over the last 5 months since this started.
Currently due to see a endocrinologist and diabetes specialist soon since being referred by my doctor. I think they suspect it is Diabetes insipidus a very rare condition, not related to Sugar diabetes. Which would make healing very difficult as you simply cannot get properly hydrated with that condition.
I will be devastated if I have actually caused this by fasting. It sounds like one of those conditions no one knows much about or has any idea how to try and heal naturally.
Fingers crossed it's something simpler that I can sort out myself.
