Clindamycin Hydrochloride and intestinal problems

I am a 38 year old female prescribed clindamycin for a tooth abscess and it is the absolute worst. The main issue is stomach/intestinal problems. Unless I take it with a lot of food or some Pepto-bismol, I will puke after taking it. Also, my stomach is so bloated, I look like I'm pregnant, not exaggerating! Also, it makes you reeeeallly lethargic and I've completely lost all my energy. The only reason I am not stopping this medication is because my tooth is really badly infected, but it you do have to take it, be warned--it sucks!
