It seems like you are talking about disorganized thinking.

The way it happens for me is similar to accessing the hard drive on my computer when I don't have enough RAM memory. If I don't have enough RAM it doesn't matter what is on my hard drive, I hit the "enter" key but nothing happens, or it happens so slow it may as not be happening.

When I am sick from detoxing and experiencing something beyond brain fog, I keep going to my mind to access data, sort facts, plan events, etc., but nothing happens.

When I get better this strange ocurrance stops. It will often come and go depending on where I am at in my detox/illness. If that is true for you it is probably simply a matter of either waiting for your body to adjust to the detox, or reduce the level of detox you are doing.

What happens when you stop the detox for a period of time?
