I just realized I didn't post an update about the dex. The nurse never called me back about it, which, in this case, is FINE. My results were stable -- at least stable enough that going dex-free for four weeks wasn't going to harm me. Dr. GPO knew this was my plan, anyway. So I went ahead and stopped the dex.
Maybe that's why I haven't had time to post an update: I've been living my glorious dex-free life! I guess it's pretty much the same as my dex-filled life, only I'm much more of a joy to be around on Sundays.
