I have had surgery for my allergies and nothing has worked.
Until I tired some Chinese natural remedies.
this might sound nasty but trust me it works.
Eat one Garlic Clove a day. You must chew it, that's how it opens up you sinus’s. it's really harsh so try to eat it with in a span of an hour not all at once.
To get rid of the bad breath, eat lemon with salt.
Drink some Eucalyptus Tea.
Rub a dab of some Eucalyptus or Peppermint Oil right under your nose (not in your nostrils or you will burn the fuck out of your self)
Take Cayenne Pepper, chew a lil bit or put it in your food.
Only do one remedie at a time, so you can figure out what works the best for you.
Also if you want to fuck for hours in bed take some Deer antler velvet.
Here is a good website to learn about more natural alternatives for all types of shit.
This is that type of shit you learn when your wifey is in med school.
