I think he's finally just getting that his stomach can't handle him eating like he always has. He's usually a meat and potatoes, lots of spice, hearty eating kind of guy. He also loves to cook so the adjustment has been hard. Also, he hates feeling like a "patient" so the fact that he has to eat oatmeal and uninteresting food lately is wearing on his mood I know.
I know he was supposed to see the dr last week so I'll see what the results of that are. I've just been wracking my brain for blandish, easy on the tummy foods that still have some flavor. I also realize I've totally thrown myself into this "project" as a way to proactively be able to do something for him. Keeps me busy and away from worrying!
