I'm sad to see that the last post here was 2002. I've been experiencing all of these symptoms for years, have had a multitude of tests done, and can't get rid of the foggy head and lethargic feeling. I feel like a pile of crap probably about 80% of the year, and it's getting rather depressing because I'm an instructor and it makes me feel VERY stupid.
I don't believe in taking drugs, but I'm so fed up now that I would probably try about anything to make myself feel energetic and able to focus.
Any of the previous people who have posted still there?
