I'm sorry to hear this, Reg. I've also had the 4-shot regimen and although I can't recall ever having had the illness, I do have occasional bouts of phantosmia where I'll smell a distinct odor of smoke but it's not actually there. It was very intense and annoying for a while when it was nonstop but it's been a few months since I last experienced it. I hope all is back to normal soon for you.
