Clarithromycin
"Obviously no antibiotic is going to be easy but this is tolerable. I am allergic to penicillin so I always get prescribed biaxin. It always clears up my infections, the only down side is the horrible bitter taste. My best advice besides chewing gum / mints in between is eat dark chocolate before & after - it actually does help subside the bitter taste! Also take the probiotic pearls with each dosage, it should help your stomach and prevent diarrhea. Eat as much yogurt as possible or drink Kefir milk -- kefir milk is the best probiotic you can take. It works wonders! You may get some minor headaches / stomach discomfort the first couple days, but let your body adjust and you should be fine. Its definitely tolerable, compared to other meds."
