hi, i have been sick and have had bronchitus.. i got antibiotics for this, and had to use the repeats.. however i still caugh (even though i told my doctor to give me stronger antibiotics since the normal once never help!) and my coughing attacks usually comes at night.. however my mucus is no longer green/yellow-ish and just today i threw up quite a lot of clear mucus in one go (thought i threw up food but it turned out to be mucus! which has never happened to me before..) do u know why this is? should i be worried?
