Dude, do yourself a favor and get off the Prilosec. Proton Pump Inhibitors are the devil. I know from years of experience. Those pills made me start to lose my hair and get a little pudge that I'd never had in my life. Oh, and they can actually create a larger problem. All that went away because...
If you want to help stop your acid reflux forever, and I mean really get it under control, you need to try Apple Cider Vinegar. Braggs or even the house brand of Trader Joe's unfiltered stuff is good. I mix 2 tablespoons of ACV with 2 tablespoons of the fresh squeezed apple juice from TJ's, throw it back real quick, and then chase it with another swig of juice. I'm telling you man, this is the way to do it. Apple Cider Vinegar is great for a plethora of things, including Asthma (makes you sleep well, too). You feel a crazy little gurgle down there, and then relief sets in fast. I was doing it twice a day when mine was really bad years ago.
If it makes you feel more comfortable, stick to your Prilosec until you feel like you're over it. Then when your treatment is done, and if you are still feeling like you have problems, give the ACV a shot. What you're experiencing is very normal these days due to the shitty food that we are all eating (unknowingly, sometimes), as well as all the other shit, too. Just my 2 cents.
