The doctor prescribed that to me too. I have gas and meat and dairy causes me abdominal pains. The doc prescribed PPI for two weeks. It was finished two weeks ago and I have noticed there's no more clearing of throats, choking and gagging. There are no involuntary reactions anymore but I still can hear people saying that sonething smells. Hopefully I am getting better. I'm no longer eating hard to digest foods, junk foods and caffeine.
