I also have a super sense of smell.  I can smell the chlorine in regular tap
water!  I can smell one gas particle if a pilot is out.  I can smell cat
pees from centuries ago.  And these smells can lead to migraine headaches.
Sometimes I would have to say I have a sort of "smell aura" before a
migraine... Crazy.

One thing I have found that really helps is to do the salt water nasal
rinses.  Strangely enough, my sense of smell seems to "normalize" after I
wash my schnoz out!

Good luck to you

Yes I smell thing nobody else does and the smell of silly things make me
want to puke! Yes on the food most of the time I cannot eat tnything I
smell!
the neighbors exhaust from lawnmowers (ours is electric) and the animals
really reek... last summer I smelled watermelon everywhere and we did not
buy any or grow any, but even in the country I could smell them

The taster is really weird - everything tastes contaminated (I eat mostly
organic and mostly simple things) oddly I have to have garlic in most
everything - or peppers or cinnamon - coffe tastes like sewage some
mornings -  by late day I can sometimes stomache something, but it can be a
real challenge and then when I try to ponder what to eat when I know I
should eat something it makes me so nauseous and therefore weepy

Advil screws up my sense of taste. Eventually everything tasted like a piece
of rebar so I quit taking it and it still took months for my  taste to
return to normal. I will never take Advil again! Not a single dose.

Oh definitely.  Methotrexate made everything taste foul.  Worse, I
had that nasty taste in my mouth within minutes of doing the injection
and it just would not go away for at least a day or two.  Lasix (diuretic)
can make things taste funny too, if I've let it wash too much potassium out
of my system.  That's how I finally figured out when I desperately _needed_
to go take my K-Dur right away, rather than at my regular dose time.  Opiates
can also affect your sense of taste and smell, as well any number of drugs
used for chronic pain.  Now that I'm back on a higher dose of Baclofen, I
can tell it's messing with my sense of taste again.  Topamax made my tongue
feel numb when I first started taking it, but that's gone away now.  

I react strongly to mercaptins (the stinky component in skunk spray and
some cheap perfumes) and to d-lemonene (the solvent in citrus-based cleaners
and--you guessed it--cheap perfumes).  Anything that contains even a small
amount of those compounds will burn through my sinuses like fire.  Worse,
too much d-lemonene exposure will cause me to start getting nose ulcers and
nose bleeds.  So when I start smelling *blood*, it's usually not a phantom
smell.  In fact, the fumes from some of those orange-based cleaners is enough
to make my face break out in that pretty butterfly rash we've all seen.  I
try and avoid the stuff if possible.  Unfortunately, some people have almost
no sense of smell at all and seem to think that bathing themselves in cheap
and nasty perfume is a fine thing to do.  And the cheapest perfumes usually
use d-lemonene as the solvent.  So I keep my migraine medications on hand
and try and flee such people as quickly as possible.
