Another technique you can try to cut off the dizziness upon standing is flex your abdominal muscles as soon as you feel it coming on. Works 100% of the time for me. Probably works for the same reason (blood pressure), but easier than hyperventilating :)

Yep, the valsalva maneuver against a closed glottis works great for this.

This is the most HN comment ever. Love it. Merry Christmas :)

During the Valsalva maneuver (i.e., exhaling against a closed glottis or bearing down as though to defecate), intrathoracic pressure increases and leads to increased arterial pressure as a result of increased afterload. It is easily done by having the patient take a deep breath, put their thumb in their mouth with closed lips, and attempt to exhale without expelling any air.

Thanks for this suggestion, I have the same experience of lightheadedness upon standing up (very often) and will definitely be working this into a habit.
