We sometimes buy the very low end wine from Chile and I think because of the sulfites in it, it causes me breathing problems. Of course, I don't make a habit of buying it, but when money is tight and at US $3 a bottle, a little hard to pass up.

Sulfites stop the fermentation process, it kills the yeasts. When something containing sulfur is fermented, sulfites form naturally. When something is dryed, sulfites form naturally also. Things such as dried fruit naturally have sulfites. When you pickle onions sulfites are naturally formed also. That helps to preserve the pickles.
To make sure the wine keeps at the say seven percent, they stop the process by adding sulfites. Blame the government for this, exact alcoholic content has to be listed. Naturally aged sulfite free wine is available and the alcohol content increases with age.
Sulfur dioxide was first used in winemaking when the Romans discovered that if you burn candles made of sulfur inside empty wine vessels it would keep them fresh and prevent them gaining a vinegar smell. 2000 years later sulfur dioxide, or SO2, remains without a doubt the most important additive that is used in winemaking.
Used as both an antimicrobial agent and antioxidant, winemakers find it indispensable to preserve wine quality and freshness. However, if used improperly, the effect can be just as adverse as they can be beneficial.
In a chemical reaction where sulfur gains electrons it is said to be reduced. Compounds that are made up of reduced sulfur are called sulfides. Sulfide compounds are characterized by a strong unpleasant odor.
Hydrogen disulfide (H2S), is a wine spoilage compound that has an aroma that smells like rotten eggs. It can have several causes, but it is most frequently a result of residual sulfur dust present on grapes when they are harvested, being reduced by yeast to H2S during fermentation.
Hydrogen disulfide can also be caused by a shortage of yeast nutrients during fermentation. H2S can undergo further chemical reaction to form compounds called mercaptans. Mercaptans also have strong unpleasant aromas that are reminiscent of cabbage, garlic, and skunk.
The Food and Drug Administration estimates that one out of a hundred people is sulfite-sensitive, and that 5 percent of those who have asthma, like Karen (who asked that her last name not be used), are also at risk of suffering an adverse reaction to the substance. "By law, adverse reactions to drugs must be reported to FDA by doctors or pharmaceutical companies. But with sulfites and other food ingredients, reporting is voluntary so it's difficult to say just how many people may be at risk," cautions FDA consumer safety officer JoAnn Ziyad, Ph.D.
If you have asthma, have your inhaler with you when you go out to eat. Similarly, if you've experienced a severe reaction to sulfites in the past (such as breaking out in hives), carry an antihistamine and make sure you have handy a self-administering injectable epinephrine, such as EpiPen, so that if you have a reaction you can stabilize your condition until you get to an emergency room.
Blame the government for this, exact alcoholic content has to be listed. Naturally aged sulfite free wine is available and the alcohol content increases with age.
So eating oatmeal the morning after drinking wine can be beneficial to get rid of the sulfite headache.

I like the last option...the only problem is sooner or later you run out of wine....unless you own a vineyard. Red wine also contains another chemical that some people can't tolerate, it is not in white wine in nearly as much quantity. This chemical makes me puke. I know a little about this chemical, enough to not drink red wine. I suppose that it would be beneficial to buy your date red wine, as it can make them more submissive.

Here in Texas you can go to Trader Joes and get a solid bottle of wine for $3. "Three Buck Chuck".
ETA: you can also find some swill caled "Cul De Sac". It smells like fart. I won't drink it. It costs about a dime less than 3 buck chuck.
