Glad your symptoms are better but I have been told numerous times by rheumatologists that the level of ANA dies not correlate with disease severity. Or with flares. And people with an ANA if 1:5120 can be healthy while someone with 1:320 can be very ill. I assume your SED rate and CRP have gone down?

Melatonin does not work for me.
I gave up several foods after an elimination test, 20 years ago. Dairy and gluten are big ones.
I do tai chi and quigong.

The real signs of progress are your reduction in symptoms. Thanks for sharing with the rest of us.
