... I take it for a fib. Fifteen minutes to one hour after rising in am I feel a surge, I get light headed,increase ear ringing, and feel nervous. Sometimes pressure over my eyes. The nervous feeling doesn't, stay long. I can be light head for three hours. It does seem to get better as the day goes on. I had over a week of almost no light headedness. However, it is back and it is worst in length. Anyone have similar problems. Doctor assures me I feel normal again. Thank you
