Hi Stuart
I have been suffering from gastroparesis for around 3 years, it gradually got worse as time went by and I know very well what it feels like, constant nausea, throwing up at just the very thought of it, a living nightmare, there seemed to relief.
I developed this condition because my diabetes was uncontrolled at the time, with my bg in the 20s sometimes higher, definitely never lower, even when I didnt digest food anymore my bg remained high.
Eventually I was so ill with various neuropathies I was admitted to a clinic, there they gave me no medication for gastroparesis, instead I was given some soothing herbal tea with a small spoon of manuka (dont ever dissolve this in hot water, has to be slightly cooled), usually it was fennel and I was told to sip this very slowly, a small cup at first, I then progressed to home made cup a soup style, just like some vegetable broth, then liquidised, I found that I was able to digest this quite well, at least I wasnt throwing up so much any more, still not perfect, I was given supplements of flax seed oil, then other vitamin/minerals and as my bg levels became more steady/dropped things became a lot better.
I was told that my neuropathy was a combination of things, first of course was the constant high bg, but also due to lack of vitamins/minerals, not only due to diabetes and medication I was taking but also the junk food that I was living (living???) on at the time.
There was another guy in the clinic at the same time as me, also with gastroparesis, he responded recovered too.
Definitely no fibre or salads, raw veg or fruit, etc - try herb tea and cup a soup things, sip slowly and only small amounts at a time and check if you could be suffering from vitamin/mineral deficiences too, you can have these even if your diabetes is well controlled.
All the best
Karen
