I don't know what is wrong with me. I was extremely lethargic yesterday and it continues today. I have been sleeping 7 hours, but I just feel like I am not sleeping at all. I wake up dragging my foot behind me. At work I can't sit and do anything for any length of time without dozing off. I even caught myself dozing off during a clients quarterly meeting with her guardians. I must be still fighting off this flu. I was off work week before last with the flu. Anyone else go through periods of time of being real tired?
