Specific diet?

[JayCS]

After low oxalate diet, I'll try some of these things you mentioned.

Good on ya - I'll cheer you on! .
I support that more important than pondering on any "best" treatment to try is...
just to do one we feel like doing, cos then we'll be most motivated, and that's crucial!
(Unless it might be harmful and something else less harmful, and that here is absolutely not the case.)
