sinusitis
"I've suffered from chronic sinusitis and post nasal drip for a while now. Biaxin is the only drug which worked for me, my PND started decreasing after one day and my nasal passages were completely clear by day 4. As for side effects it increased my appetite and sent me to the bathroom more often than usual. As for the nausea and metallic taste in mouth that most people reported, that only occurred on my last day of treatment thankfully. It's a small price to pay for the relief I got however."
