I'm in the same boat. After a while you get used to it. I think back to
when I used to have 2+ bowls of rice for dinner every night and wonder
how I did it. Slowing metabolisms suck.

Sometimes I mix short grain and brown rice but cooking times can be
tricky since they have different cooking times.

Tofu noodles? I've never heard of that one. There are Bean curd sticks
(Chinese: fu jook pin; Japanese: yuba), but I wouldn't quite describe
them as noodle-like.

Konnyaku noodles (aka ito-konnyaku or shirataki) is very healthy but
just not the same.
