i'm quite as shocked.

if it's serious and the problem is prolonged better be safe than sorry la brother. I myself take coffee everyday to and have no problem with my bowel movements, but if u find your case is genuinely strange, you will need doctor's help for expert opinion or get yourself analysed better medically by them.

wow really? wtf? u have allergic reaction zit? try consult doctor le, like srsly allergy scratch test or something better than just making a guess of how to manage ur probs.

not really necessary, if u r sure that u r allergic to something, like i'll have headache if i consume lamb, im pretty sure bout it i just dun eat lamb that much la, but in your case if the allergy could cause something worse than headache, u might never know, so all ur life if u take coffee u'll have breathing problems?
