No. I do that kind of thing all the time....
Well... perhaps I have "lost it," whatever "it" is ... but I mess around with variants on names a lot.
Other ways to spell it - ?
Adrena
Edrina
Edrena
Adreena
Personally I find Edrina very appealing. The Adrin- and Adren- remind me of adrenaline, and Audrina looks like aah-drina or aw-drina to me, instead of uh-drina like you say you're pronouncing it.
