It is so weird. The first night he had it, he woke up very agitated, wordless, distressed; I thought it was either meds or nightmares.
2nd night, agitation was much, much worse; he was up for 2hrs, all squirmy and babbling like a drunk.
Next morning dr said this was classic adverse reaction (makers list anxiety, restlessness, sleep interruptions) and not to give 3rd dose. A month later ds is still appearing every night in living room an hour or two after bed. Looks awake, doesn't say anything much, goes back to bed usually with a little moment of agitation, then quickly back to sleep - but have just discovered he has no idea he's doing this. No memory of it at all.
He's never done anything like this before, ever. Weirdness, coincidence, or what?
