I haven't been keeping up with my Facebook friends at all. I got my vaccine yesterday! No prior appt. until yesterday. My husband got on the computer and contacted Kroger. They told me to be there within the hour. I got it and was very happy. Then later I looked at my mail from my insurance company. It stated I had a prednisone shot in December. I had a terrible night last night. I woke up wondering how long prednisone stays in your system. I had the shot on December 1. I took a lot of it in tablet form this summer for nasal swelling. Anyway, I do suffer from anxiety in addition to many other things. So, I woke up at 2:30 am and got on the computer researching how long this lasts in your system. Only hours, from what I read. I hope it's true. I feel foggy now. I know I need a good night's sleep--I haven't had one in years--due to sleep apnea. Can't wear mask--can't breathe through swollen nasal passages and severely deviated septum. I haven't had any reactions from the vaccine. My arm is sore anyway.
