What a difference a few days makes form being on top of the world to what the heck hit me, picked up a sore throat and cough, checked not corvid, so treat as a cold, Wrong ten days later rang surgery, doc rang back come in the next 20 minutes need to listen to your chest, now on antibiotics! I never realised what a weakened immune system meant till now, also didn't realise how energy I had before honest I won't complain of lack of energy due to meds
