Your experience was somewhat paralleled to mine. I didn't have any respiratory symptoms but the fever, malaise, weakness, and disorientation were significant. For a day and a half I couldn't even get out of bed to relieve myself, drink, eat or take medicines. My family and friends sent the Sheriff's department to me for a "wellness" check. I finally was able to get up, clean up, drink and take medicines. I forced myself to walk to the mailbox and do menial tasks. I was determined to either die at home or get through this. I will not take the mRNA shot as I was an experimental subject for a failed vaccine experiment back in 1974 while in the USAF.
I lost 25 pounds, lost lots of hair and have multiple dental problems from the event.
