Dale came up allergic to something last night. I have no idea what, but at some point after I went to bed, he woke me up (a bit) to say, "I'm itchy and my chest feels kind of tight." I vaguely remember saying, "TAKE BENADRYL. NOW." I guess he did, because he's up and at 'em this morning. I was apparently sufficiently aware of this that I woke up periodically through the night to make sure he was still breathing, but not sufficiently aware to actually wake up and ask what the hell was wrong.
I'm very glad this didn't end up with another trip to the ER.
