Anacrusis
How fascinating this subject is I went three years before my MG fog started I call it that as that's what I think it is and how horrid it was it kind of destroyed my confidence the Dr did a basic memory test so stupid it was I still got the wrong day thou mine was always after pushing myself I would become confused didn't know simple things what hurt was would cook the total wrong food not able to do the most simple thing thinking I was seriously becoming crazy seems a lot of us also have had the symptoms
