I've had an acidity issue for around five years.Other pathetic medications were tried, but they weren't very effective.I used to experience acid reflux between two and three in the morning.Sleep is disrupted by a heated feeling in the throat, a sensation of acidic liquid moving towards the nostrils, and a feeling of vomiting.I took one Ranitidin 150 tablet before bed around seven or eight months ago, and now everything is under control.I can't avoid the iPad anymore, though.Without the tablet, symptoms worsen, make it difficult to fall asleep, cause vomiting, or require drinking water to relieve symptoms, all of which prevent sleep.Managing the daytime is not too difficult.How long may I take the medication mentioned above?
