Clarithromycin
"I was prescribed 14 tablets of clarithromycin for a painful tonsil infection/ tonsillitis. I'm on day 5 of takin the pills and my infection was cleared up on day 4. It was effective in destroying the bacterial agent but there are side effects. Bloating and gassyness, diarrhea, adrenaline rushes and insomnia. I've been hyperactive late on the night and barely slept the past 3 days."
