I have read articles on cfs that explain that people who have cfs react differently to anesthesia than healthy people. They sleep a lot longer before they wake up from the anesthesia. We always thought my daughter had cfs until she was diagnosed with lyme. But now I am not so sure that she doesn't have both cfs and lyme because I recall that she slept longer than any dentist had ever seen anyone take to recover. Does any one know if people with lyme also react differently to anesthesia? Thanks.
