helicobacter pylori infection
"Today is my 5th day of taking the medication.  I too was worried about taking it after reading some horror stories regarding the side effects.  I am happy to say that so far the only side effects that I've experienced is a little tiredness the first day and the bad taste in my mouth which I've noticed that I've experience more in the middle of the night upon waking for various reasons.  All in all I am pleased, other then the fact that I have to take them for 14 days.  Good luck to all!"
