gastroenteritis
"I have suffered with gastrointestinal/irritable bowel syndrome problems for 15  years. This medication is literally a "miracle worker". Anytime I have a flare-up that causes nausea/vomiting, I take one pill of this and I am fine just minutes later. I remember thanking my doctor over and over for finding this medication for me. I agree with others that it makes you a little sleepy (does not knock you out though) and also if you use it several days in a row (which hopefully you do not), it can and may cause constipation. I would recommend this to anyone with frequent and/or recurring GI/IBS episodes."
