I just made an appt. for a sleep study and was wondering what to expect. Actually I am a little nervous about it. I really feel like my sleep issues are a big part of why I feel so foggy. Back when I did work, I miss those days, there were many times when I had to work late into the night and return the following morning. I always felt so foggy those days. My senses were not clear on those days, just like today.
