sinusitis
"Took clairthromycin for four weeks 500mg 2x a day which seemed to strong to me.  Same metallic taste a lot of people get, it is medicine so I expect that. It gave me dizziness, tiredness, and nightmares galore, I have lost of sleep from all the nightmares. I actually felt really out of it.  I took probiotics, and ate yogurt, and after I stopped taking it three weeks later, I began have severe stomach pain, I have read it can cause so serious issues with the liver so now I'm off to the GI doctor I wish there was something in medicine that could cure us without any side effect like Royal Rife invention"
