Purps, this may sound crazy because I thought it sounded crazy, but you should check out accupuncture. I thought it was just for stress relief but Traditional Chinese Medicine is fucking insane. Apparently your body has 12 meridians that run through your body, and when you're allergic to something, a meridian is blocked. To unblock the meridian you use accupuncture.

I have athsma and I had really bad environmental allergies. I used to wake up and sneeze about 20 times and blow my nose for 15 minutes. That's all gone. I feel like an ex-leper. Obscure Life of Brian reference anyone?

But I also had allergies I didn't know about. Not really allergies per say, but I had slight reactions to corn, milk and processed sugars. And I always noticed after I ate corn or milk, my stomach was always a bit off for a while.

Try it out guys, I'm a real believer in TCM. They've been around for a long ass time and there's billions of them now. They obviously know how to survive.
