JazakAllah for the nice post on Sunnah.
I believe it is also a Sunnah of Nabi paak sallallahu alaehi wa sallam to:
Use your right hand (to hold the glass/cup etc.) while drinking water.

I think the Sunnats mentioned also apply for other drinks such as tea, juice etc.
Allah subhanahu wa ta'ala knows best.
