I'm learning a lot from this sub. Things I didn't think were symptoms that I can now see probably are. I've been unable to find knowledgeable medical care so I'm largely left to figure things out myself. Thus, I don't have a lot of helpful advice but here goes.

I should say that I think I'm probably in the low to moderate sensitivity range.

Migraines: helped by a low histamine diet. I rarely "cheat" and only take NaturDAO when I can't avoid a food I'm mildly sensitive to, or I have alcohol. I still react but I think less severely.

Insomnia: also the low histamine diet

Inability to lose weight OR gain lean mass: can't explain this one but I'm adding it to the list of body chemistry issues. I haven't been able to address this.

Ache in front of quads and hips: again, no real solution but salt seems to help. I have a salty meal, like Asian takeout/away.

Bloating and rash on neck at even the thought of food: don't know how to fix this. I think I'm more stressed than usual but I've been unsuccessful in fixing that as well.

I'd also add poor bloodflow. I exercise regularly (weights and a very small amount of cardio) and it doesn't seem to help.
