has anyone else been diagnosed with copd after stopping smoking ? its just that I was great after stopping and then went all breathless ect . its been nearly 3 year since I was told it was copd . but I have been monitoring myself and iv come up with the conclustion I have a food allergy . now iv looked up the food s and its the deadly nightshade foods .pots tom foods with seeds in . I kept getting a in flamed throat .blamed my meds ie inhalers .but even drinking a cup of water . wasn't really making any difference . now this deadly nightshade is also found in tobacco and I smoked heavy at times . so now im thinking the tobacco was keeping my body used to the allergy and when I was taking it . the true allergy has came out . even certain teas make my throat inflamed and I go slightly breathless but if I keep off the foods and tea etc I have a great day I even papered my dining room . now isn't that wonderfull . has anyone else looked into this or found that food etc causes things .
