Clindamycin
"This drug reminds me of Vicadin. Which isn't a good pain drug because of the continual dosing.   You have to continually take this clindamyacin 4x a day and I'm not waking in the middle of the night for the 4th dose!  Ridiculous. My day is number 5 and my temples are sore.  Side affect, maybe.  Next time I think I'll ask for the more powerful, with less doses per day.   Two doses per day, the old school way, would be better.  This is on my DO NOT TAKE LIST!."
