I began to suffer from acid reflux symptoms in the week after Thanksgiving. On 21 December, I went to a doctor and gave me Prevacid. I've been taking it since then. I started feeling much better a week after you start taking the medication, but my symptoms are not all the way gone. Sometimes I still feel I have a lump on the back of the throat and I burp a lot. Occasionally I'm a little nauseous. How long usually take to recover from acid reflux, or do you recover at all And when I run out of medicine, I must be good then, or I need more I have enough for a month and a half. I have plans to return for a checkup later this month, as well as my doctor asked me.
