My immune system is in a very bad state. I'm pretty sure I have overgrown yeast and it feels like I've had a cold for over 6 months. I never really recovered after all the Antibiotics I stupidly took when I has Sinusitus. I'm starting to worry now coz' I don't seem to feel much better after being on a really strict diet for weeks. I can't stop coughing. It's even the Echinacea tea making my throat sore I think. Thank you for your responce but I think I'm gonna' just drink more water. Don't know what to do and my GP just seems like the enemy.
