Hie there
I have only been on prilosec for just four weeks, I am eating for an elephant.
I am hungry all the time, so I think your question is answered.
As well as taking the prisolec you need to watch your fat diet.
I am watching my fat diet and my acid diet.
It is not as bad as it seems.
There are lots of low fat diets and lots of low acid diets that let us eat ordidnarily.
Good luck to you.xx
