Personally, I would try just the prilosec first and see if it helps the n* too. The zantac always takes away my n* - I never need to take anything else with it. Phenegren causes drowsiness, so I wouldn't take it unless you really think you need it because you will probably be out of it for the rest of the day. Try the prilosec, find something to get your mind off of your stomach for about an hour, and see how you feel after that. You probably will find that you won't need the phenegren. Hope this helps!
