How do I reduce my alcohol allergy?

A moderately potent kava drink causes effects within 20–30 minutes that last for about two and a half hours, but can be felt for up to eight hours. Because of this, it is recommended to space out servings about fifteen minutes apart. Some report longer term effects up to two days after ingestion, including mental clarity, patience, and an ease of acceptance. The effects of kava are most often compared to alcohol, or a large dose of diazepam.[1] The sensations, in order of appearance, are slight tongue and lip numbing (the lips and skin surrounding may appear unusually pale); mildly talkative and sociable behavior; clear thinking; anxiolytic (calming) effects; relaxed muscles; and a very euphoric sense of well-being. As with other drugs that affect the gaba receptors, there can also be paradoxical dysphoria. The numbing of the mouth is caused by the two kavalactones kavain and dihydrokavain which cause the contraction of the blood vessels in these areas acting as a local topical anesthetic. These anesthetics can also make one's stomach feel numb. Sometimes this feeling has been mistaken for nausea. Some report that caffeine, consumed in moderation in conjunction with kava can significantly increase mental alertness. A potent drink results in a faster onset with a lack of stimulation; the user's eyes become sensitive to light, they soon become somnolent and then have deep, dreamless sleep within 30 minutes. Sleep is often restful and there are pronounced periods of sleepiness correlating to the amount and potency of kava consumed. Unlike with alcohol-induced sleep, after wakening the drinker does not experience any mental or physical after effects. However, this sleep has been reported as extremely restful and the user often wakes up more stimulated than he or she normally would (though excessive consumption of exceptionally potent brew has been known to cause pronounced sleepiness into the next day). Although heavy doses can cause deep dreamless sleep, it is reported that many people experience lighter sleep and rather vivid dreams after drinking moderate amounts of kava. [2] After thousands of years of use by the Polynesians and decades of research in Europe and the U.S., the traditional use of kava root has never been found to have any addictive or permanent adverse effects. Users do not develop a tolerance. While small doses of kava have been shown to slightly improve memory and cognition, large amounts at one time have been shown to cause intoxication. In Utah, California, and Hawaii there have been cases where people were charged with driving under the influence of alcohol after drinking a significant amount of kava (eight cups or more) although some of them were acquitted due to the laws not being broad enough to cover kava consumption.

Odd. You're dead-set to overcome your body's natural rejection to one drug, and at the same time make a conscious rejection to another drug. anyway, in keeping with the search for the constituent allergen, I'd try sourdough bread. It's basically fermented and then baked wheat flour. If you eat this regualry as well as some steamed barley, your body would get used to it. Then your body might accept beer more readily. Forget the hard liquors for now, and I know a bunch of people who can drink anything, but have bad allergic effects from wine.

If I were less responsible I'd say "Just drink through it", however sometimes you just need to accept the hand you've been dealt. Some people have a reaction to peanuts, some to gluten, you're body has a reaction to alcohol. That's really the end of it. Despite the backlash from BeanGolum's comment, this is probably the best approach. You obviosly have no qualms with getting wrecked, so really it's your drug of choice. I think marijuana is the best option for no other reason than it is the least damaging drug out there. You can overdo it on anything though, so be smart about it no matter what you chose.

*seems to work pretty well... I get hay fever in extreme every few years, to the point where it really is a bit debilitating, I found that nasal sprays ere far more effective on all symptoms and helped my brother who got skin rashes if he got grass on his back or bare skin. In recent years the hay fever thing has been subsiding though...
