I was going to post this on the "False Posts" thread but realised it would be a threadjack
In my experience, computers and the amygdala don't mix well.
I can handle anything from 1 min to 1 hour a day in front of a computer during which symptoms will build to a crescendo, and there's always a period (two mins to two hours) of the symptoms gradually abating after sitting in front of a computer.
Symptoms are much worse if I'm sitting using the machine for no good reason: ie chasing a lost cause (eg trying to figure out if something REALLY works based on forum posts!) or just wasting time (reading football news).
In the past I was a computer programmer and spent far too much time staring at screens trying to solve very complex problems so I expect my Amy is extra sensitive to computers, but I expect most CFS...sorry Retrainers(!) will have the same thing going on to some extent. Humans are not evolved for extended computer use.
Raymond Perrin of the Perrin technique points out in his book the connection between computer use and CFS, reasoning that it's very hard on the spine (the basis of his CFS thesis). I'd add the Amygdala-baiting side of computers to that.
Aside from all that, the depersonalising and in fact pathological effects of internet forums, blogs, chatrooms etc have been academically studied.
Bizarrely, I find I have a similar problem with newspapers! Well i guess if I wanted to think about about a bunch of lies, omissions and deceptions I'd just listen to my thoughts...
