For about 2 weeks I have been experiencing flu-like symptoms but only at night. It starts off with a sudden hit of fatigue in the evening and then body aches get worse at night but never a fever. In the morning I feel fine again. I did a monospot test which came back negative a few weeks ago but I did have mono about 4 years ago. I'm tired of feeling like this all I want to do is lay in bed at night. I did go through a period of anxiety that started in september and I am still experiencing anxiety just not as worse as before its slowly creeping away. Has anyone experienced this before?
