bacterial infection
"I had a wisdom tooth removed and developed an infection in my jaw. I was prescribed 1200 mg of Clindamycin a day. 
 The pharmacist warned me that I should take with plenty of water, which I did. I also took it with food. 
  The first time, I had to take 56 pills. Second time, 40. I just started another 56 pill stint of Clindamycin. I have had absolutely NO problems because it was stressed to be taken with PLENTY of water. 
  Now, as far as the infection goes, I don't seem to be recovering from it even after having my jaw reopened and the bone scraped. I am very scared of what else this infection could do to me more so than the Clindamycin. 
  Please take it as advised by the pharmacist."
