Acid reflux?

I've been dealing with acid reflux for 20 years. Now I am hooked on prilosec.
Sometimes I wake from a dead sleep with what I refer to as choking-hot-puke-in my throat. For the first couple seconds I feel like I'm dying. Just two days ago, I had an Endoscopy for the first time. It's an imaging tube they stick down your throat and check out your esophogus (sp) and stomach. Nothing showed up!
Sooo. either I stop smoking and significantly change my diet, or just keep taking Prilosec. It blows.
