I am 60 years old and I had mono about 7 years ago. I got it again this last mid-March and I keep waiting for it to go away. It is less severe than it was but the fatigue is annoying. Originally I could hardly hold my head up without getting dizzy. Now I can engage in some kind of activity for 15-20 minutes before I have to quit. Usually I put my head down which seems to help. This has been going on for 8 weeks and my Doctor says that there is nothing that she can prescribe or do for me. Does anyone have a similar situation going on ?
