I play most other games (Asgard's Wrath, Walking Dead) with continuous movement.
I find in Alyx, I prefer blinking. Will totally solve any nausea problems you are having and, honestly, you lose nothing.
As the devs explained in an interview, people tend to "edit" out movement in their heads; i.e. running from place to place in HL2 is not the import of the game.
They've really nailed the Blink movement.
