Little gluten update

So we are now on our Easter holiday trip going down to Strømmen and Oslo
Had a quick stop in Kvam at my grandparents house.
To be polite Eric had some cake with his coffee.
About 45 min after he got a heartburn.
So from being off gluten for so long he is now starting to notice every time he has bread products he gets a heart burn. Something he used to get pretty much everyday since he was a kid. Since going paleo ( most of the time ) he might have had it 5-10 times when eating bread and maybe if he has too much coffee.
