The OralChroma is pretty expensive though, so I would prefer to split it with a few fellow sufferers from the UK. Last time I checked (a few years back) they were about £3k. So about £500 each if we get six of us together. Or maybe we can source a 2nd hand one.
We can, for example, keep it a month each at a time.
I think it will be invaluable in determining what helps and what does not, in particular regarding diet.
Please let me know
