I've been adding glycine to my bone broth (aids with cartilage production). Tastes sweet with bad aftertaste so don't overdo it unless you don't mind choking down sweet broth.
I've been attempting to get my sleep optimized in a big variety of ways. I've only done it one night so far, but mouth taping looks like a prime candidate for best intervention based on preliminary reports. Optimizing sleep could be the missing piece of the puzzle for your body healing itself.
Do you supplement with omega 3/DHAs?
