I like a nice long quiet period after Communion, when I can rest in the Lord's presence. Adoration, not so much. The Sacrament is for receiving.  Praying to it, other than as part of the ritual of the Mass (like praying Eloi Eloi lama sabacthani at the first elevation or I thirst at second) is turning it into a hidden or visible icon or idol (if you are an iconoclast). I can pray to the every-present God anywhere.
