Or do they sometimes wake up at night with not necessarily heartburn but with kind of an acid taste in their mouth, particularly, for example, after a late meal. And I think almost everyone has experienced that. And that is an example of how a normal individual can have gastroesophageal reflux. So what we recommend to patients, for example, is don't go to sleep until you've had at least two hours after your dinner meal, and so forth. So there are issues along those lines related to both food hygiene, if you will, or eating hygiene that relate to sleep hygiene.
Antacids are useful.
The problem with antacids is they don't last for very long and they are usually treating a problem after it's occurred. For example, it's closing the door after the horse is out of the barn. What you would like to do - because the reflux has already occurred and the antacids are taken after the person has a conscious perception that they have heartburn or that there is something wrong there. What we recommend is that individuals just go to the drug store and buy Pepcid or Zantac or one of these over the counter H2 blockers, the histamine blockers that are acid suppressing drugs. And if this is a chronic problem for individuals, some individuals, in fact, need it almost every night.
