This is just my personal experience. I don’t know what is best for you. Discuss options with your doctor, okay??
I have asthma since I was about 18 years old. I have been allergic to everything under the sun for as long as I remember.
No, I am not kidding. You name it, I am allergic to it. Candles are horrible, lilacs about kill me (though I love them) and lets not even talk about laundry detergent. However, one day I got some advice. I was told to try removing dairy from my diet. Wouldn’t you know, it worked.
