Please, everybody, keep in mind my qualification: 'for lack of a better word'!!!
'Lost in translation' might not directly apply here, but I am ESL (English as a second language, might be a Canadian term).
I didn't mean to offend or attack any one in particular. As I said in my next post, I might be overly sensitive to this topic. I don't know what is going on so much in other threads - I am new to PR and this is the only thread I am really following. So I really apologize if I came across a bit brush. I am very direct, but since I am new here, you guys don't know that. I am also German, what can I say

? If I offended anyone, please forgive me!!!
As an aside, due to my symptom severity and difficulties when being upright, I type all my posts on my phone while lying down. It takes longer but requires the least energy. But it also means I don't elaborate as much as I should when I comment on things (which might be a good thing...?).
I am deeply in awe in what you all know and the level of understanding of and insight into ME/CFS you have. That is what kept me reading the entire thread - and rereading it.
To get back to the real issues: I get PEM from pretty much everything: emotional, cognitive, sensory, or physical overload. Two lunges and I feel it the next few days. I am practically bedridden - leaving the house about once or twice a month in a power wheelchair. Yet I have been able to eat yogurt and take most prebiotics I tried (except for baobab powder). I went dairy-free for about a month and when I went back to eating yogurt, didn't feel any worse (and as bad off as I am, I know it can get much worse still). I just got VSL #3 in the mail and will report on how that affects me. So far the probiotics I tried where the SBO based ones, as well as some individual strains (L. Plantarum, Bifidus infantis, C. Butyricum).
I also have POTS and tachycardia, meaning my heart rate goes above my AT threshold when I have a bad dream or turn around in bed. Since I am more active than that (not a lot, though), I am pretty much always overexerting myself, so part of my problem is that I have constant PEM, I think. Initially, the PS lowered my resting heart rate quite a bit, but, sadly, that effect didn't last.
