For everyone suffering from terrible reflux I have finally found the solution to mine and wanted to share.
It mightn't be the same for anyone else but just in case it is.
First of all - new, bigger bra. Improved reflux a little.
Cutting out gluten completely from my diet - no reflux at all since.
It has given me more energy and I have had no headaches and been able to sleep better.
Hope this helps someone!
