I know, my translator timed out. Here it is: "Doryx contains doxycycline hydrochloride. Inspection at LV's laboratory has shown that a large part of the substance is released within ten minutes at high pH. If the Doryx capsula would get stuck in the esophagus can Darfs the high concentration of the agent quickly lead to injury. There are no reports of esophagus injuries for Doxyferm (doxycycline monohydrate) available on the master list, or for Vibramycin." Still vomiting isn't that fun. I'll look in to it. Thanks! I took 25 mg of Doxy yesterday and today and am already feeling a bit better. Hope it won't be as bad this time.
