Azithromycin
"It definitely works fast on bacterial infections. I've used this medicine twice. In my most recent event, I was sick for close to three months with a gurgly wet and sometimes dry, wheezy cough with fatigue but no fever. The doc called it bronchitis when I first got sick and we tried a 10 day amoxicillin regiment with no improvement. Over the 12 weeks, the cough mutated into three different variations including a sinus infection. I finally went back to the doc. After starting the 5 day regiment, I noticed an improvement within the first 12 hours. In both cases I was nearly 100% healthy by the 3rd day. The antibiotic is very stressful to your body. I experienced extreme fatigue and muscle soreness during the regiment, but it was worth it."
