What an encyclopedic anthology of anecdotes and reliefs for this subject! After reading so many peoples’ experiences, I would summarize my smell context this way:
Never smoked, only take prescribed drugs, non-asthmatic, had a really super-mild heart attack five years ago, and take a number of medications for blood pressure and such. I have virtually no work- nor school-related stress, little social stress, but above average emotional stress. One-time vegetarian, but I eat meat again now, but in my opinion not enough fruits and vegetables. Is the Smell more likely with carnivores than herbivores, or is it equal-opportunity? Medicinal (prescribed) (!) wine each day, which is sometimes skipped.
I live in a high, dry area, near the Rocky Mountains. I rarely drink coffee, but drink various teas. None of these seem to be a trigger for the Smell.
My Smell comes unexpectedly. I usually think it's a "real" smell, then recognize the familiar odor. The last couple of times it has come, it has been much milder than the other times. Right now I have it, and have had for about three or four days. So it should be gone again by Monday.

It's so mild now, it's almost ignorable.
I've read all the posts. I would like to reply to:
Smoklesslady, I have never had herpes or any such disease, and there is no increase of temperature in my head or elsewhere, so far as I’ve noticed, when the Smell attacks.
M_egan, thanks for the suggestion of clarinex and nasacort. Although I cannot take “decongestants” due to other problems I have, I am going to look more into these. I do not recall if I had the Smell before moving to my current residence, which is nearly one mile above sea level, so that could be a factor, though personally I doubt it is the cause or a strong factor.
billielengal – “
phantosmia” – it’s nice to have a name for our enemies. In my case, I just like words. -- This should make it easier to find at medical sites and in medical journals, right? Right!
Suppers – Thanks for the clues about foods. I’ll watch to see if I eat some particular category of food just before the Smell returns. However, I do know that neither skim milk nor cereal is the cause of my smell-distress. Nor does salami. But there may be another food related to this. I realize different people react to the same foods differently; so you could still be on the right track for your Smell.
catlvr14 and others who mentioned congestion and infection – I have allergies but haven’t experienced them heavily this year; years they have been worse, I experienced no Smell. However, I realize that as time passes the symptoms and reactions to a commonly established order or distress can manifest themselves in new ways. So although my allergies are mild this season, there could still be a connection. I have had my share of nasal problems, all very very minor. However, I do experience that weird clicking in the ear now and then, and sometimes it is also when I have the Smell. but both the Smell and the Clicking also occur alone without the other.
Now it’s levaquin and nasonex. Will have to look into those, too. However, I am not going to get into the habit of using a nasal spray on a regular basis. Although I’m old enough that I shouldn’t worry about the long-term effects, I am nonetheless not comfortable with that practice. I do have a very sensitive olfactory organ and sense of taste; don’t want to risk compromising them.
wepst – my Smell comes when I skip my vitamins as well as when I take them. Neither taking nor avoiding vitamins seems to help, in my case. As far as red wine goes, I have been prescribed a few ounces each day. I don’t always take it. But the Smell occurs whether I do or not.
MN-Mike – thanks for the information on
sewage sludge. Are there “
journal articles” you can refer us to??? I cannot take the usual kinds of allergy pills, and I intend to avoid nasal sprays. I would rather suffer the Smell, though I would even more rather it go away. Fluconazole, but not nizoral, you suggest, as the latter can cause liver damage; and I am already taking liver-harming medications for another ailment, so I avoid everything that warns of possible
liver damage. Thanks, MN-Mike.
mistymiztee – I have had “chest congestion” with “productive cough” for decades, without accompanying Smell. I may have something like
bronchial asthma and even also
allergic rhinitis, though have not been diagnosed as such; doctors just say they don’t know what it is. As for your other symptoms, I don’t have them. And no you aren’t losing it. This “Smell of Smells” really is a “concrete” if intangible problem.
noahemirae – Sorry about lyme disease; I hear that’s a real bear to deal with. My Smell-episodes are rarely more than a week at a time. Thanks for putting it in perspective. The Smoke-Smell is much to be preferred over the other pseudo-smells you mentioned – dead things, feces. I am blessed. (For having the ‘smoke’ version rather than a worse one.)
May the day come that we all smell nicely!
