Testimonial from group vegan beginners 101 on Facebook So... I quit all dairy about 7 weeks ago and then went totally vegan right after. Since I was 16 years old, I've been hospitalized for severe asthma over the years, suffered from chronic sinusitis.. had all kinds of digestive issues and in the more recent years, debilitating migraines. My parents were always proactive about my health, I had several asthma specialists, two allergy specialist, 5 ear nose throat specialists (who did throat and nose surgery on me), a gastroenterologist and two neurologists. I'm now almost 30. NONE of these doctors were able to figure out that I have a severe allergy to caesin, a protein found in dairy. Apparently testing for caesin is not generally on the standardized allergy testing and you have to ask for it...? (Like what parent or kid is supposed to know what the hell caesin is..?!) after about 3 weeks several of my medical issues started to resolve.. I was able to get off medications and seven weeks out my asthma that has crippled my life for 13 years is virtually gone. My sister with severe IBS also got tested for caesin, which came back positive and now her issues are gone too.
