YES!!! And sometimes it can shift and you can get into another pattern. I've had it for years. I still get it now, though for a few different reasons. No doubt partly mercury still.

Treating candida has helped, but things very easily go wrong. If I do or take anything that may not be suitable for me personally, all hell can break loose and for a long time following. I dont' bounce back.

HOpefully for you, the chelation will begin to clear the mercury so you may get more of the better patches that will hopefully last longer as time goes on. Some stability will hopefully return.

People know when I'm at my worst, because I'm on the computer so much. I just sit because I can hardly do anything else. I also find it hard to take things in. I find it hard and at times almost impossible to read a book and I find I read something over and over and I'm trying to make sense of it, even though to others it's easily understood.

The sensation of sheer stupidity and loss of short term memory are big issues. I have to repeat my questions to people because I can often not remember what they just said. It's embarrassing.
