Hi i i used to suffer badly with reflux , i put the head of the bed on blocks about 6inch high head end so i'm on a tilt , feet lower than head that way any reflux there it won't stay on the chest , it works great , take care ,
Hi and welcome to the GERD forum.
May I ask what all you are taking as part of your "liquid" diet? If you are not getting enuff calories and are still hungry that could be the cause of your headaches....try to relax as stress and anxiety will add to both your headaches and reflux.
The elevating of the bed will help with the reflux entering up into your throat and mouth....but it may not help with your headaches.
Once off your current diet you will want to modify your everyday diet and lifestyle to help prevent this happening again....
