I've suddenly (mid 40s) been hit by this, having never had it before and it's unnerving. Should I go and see the doctor or is it okay to just take OTC remedies? I've had heartburn before, but I hate the acid reflux - the horrible sour taste in my mouth, feeling sick all the time, not being able to sleep for the discomfort. I started taking Nexium today, but it hasn't had any effect yet (it does say on the leaflet to give it 2-3 days), so just popping antacids whenever the horrible feeling comes back. Should I be worried? Should I go and get it checked out? Or it is just one of those things that everyone gets?
