Large Portion

Since long ago, if there was a large portion option, I would choose it.
I used to enjoy eating every bit of it.
Even recently, I still buy large portions, but it has become tough to finish them all.
I don't eat out anymore, so I don't have the chance to order large portions at restaurants, but I still choose the large size when I buy things to bring home.
Instant yakisoba, in particular, has become difficult to handle.
A regular size is now enough for me.
I still like it because it's delicious, but it seems it has become quite heavy on my stomach.
Is this proof that I'm getting older?
Or could it be because of an illness?
Well, either way is fine.
From now on, I'll just be satisfied with a regular size.
That's that.
