For the past few days,I've been yawning a lot,much more than average(once every few minutes I feel the need).If I'm not yawning I'm breathing in as deep as I can to get similar "satisfaction".Often I cannot get the "satisfaction" from these and so the urge grows and grows, meaning it can get quite uncomfortable. When I do manage it, the urge is back a few seconds later.This is whether I'm tired or not, almost all day. I also have food Reflux on and off . Please suggest.
