If your sleep issues are a result of your ongoing recovery, then your lymph could be congested.
If your lymph is congested, then you can have symptoms like light headaches in the back of the head, light constipation, and kidneys arent filtering to their potential. This issue with the lymph will cause insomnia (which makes sense, if you are detoxing to any degree).Over time, if your lymph doesnt move,your body becomes acidic and affects all the glands.
Not saying this is it, only that I am familiar with this issue listening to Dr Morse all day,lol.
Kidney filtering herbs and lymph movers have been helping me bigtime.
