helicobacter pylori infection
"The side effects of this medication were unbearable to the point where I thought I wasn't going to be able to finish the whole 10 day course. It left a disgusting metal taste in my mouth for HOURS. Strong nausea started on day 2 or so, but subsided  around day 5. It can be best described almost like morning sickness a pregnant woman would have. On day 7 it actually gave me acid reflux, which was worrying since I thought the medication wasn't working. I stuck with it and made it to the tenth day, words can't describe the happiness I felt throwing the pill bottle away. As horrible as it was, got retested and H. Pylori is officially gone!"
