Does your protein shakes make you feel full for a long time?

I think sometimes it depends a little bit on how thick the shakes are.  If you make them very thin, they will empty out of the pouch even more quickly than a thicker shake.  Even thick shakes, though, don't stay in the pouch very long.  I never found them particularly filling for very long, but I have been eating by the clock for the past 5 years, so it doesn't really matter how long something makes me feel full.
