The only problem with doing flushes with adrenal fatigue is that it can be an added stress on the road to recovery.
Some people are not ready to make that leap.
These people will never recover as long as the liver is not working.
I see you slept well after taking the bitters. People here are chasing magic adrenal/sleeping pills for years and years not making this connection despite myself and lots of other people saying this over and over and over and over and over...
Keep taking the bitters and/or fatty meals.
Now you are ready for kidney cleansing.
Come back in a few months and see the same people talking about ssri's, overstimulation of gaba receptors, bla bla, etc, while you are getting a good night's sleep and have basically told them how to do it right.
