Bronchitis
"Day 1: bitter taste in my mouth after taking the first 500mg at night. Nauseous. Took it after a meal, then I felt sick after. Was able to sleep ok. 
Day 2: small rashes on my hand, legs, and neck. Not too many but still, they are rashes. Nauseous. Couldn&#039;t sleep at night. This was the first day of doing morning and night 500mg each. Coughed a bit in a span of one hour. Normally I cough for 2 hours when I haven&#039;t taken the antibiotics. Sleep was ok. 
Day 3: rashes, fast heart beat, shivering, feeling sick, feeling hot like having low grade fever, it is 247am and I am up. Feeling tired, my upper back hurts. Coughed a lot from 830pm-1230am. Fell asleep for a few minutes but woke up to the feeling of losing breath. Must be an allergic reaction"
