I have had several of these kind of symptoms as well. I think it is congestion of the gall and liver which is preventing the liver from clearing properly. From what you say, I would agree that a programme of Liver Cleanses may address the problem. I have just started on the same, (one flush so far), and got some relief, although I dont think much came out.
The wider question is why the liver becomes congested and there are different theories. I am also on a garlic cure right now to clear any of the pathogens that Hulda Clark sees as the underlying problem. This seems to be helping quite a lot.
My attitude is that it only takes between 3-6 months to go through the various cleansing programmes. If they can restore a good level of health, then this is not a long time. I dont see any alternative.
