So, we've been waiting for Squirrel's 15 mg prescription for Adderall to arrive. It had become clear that the 10 mg dose wasn't sufficient (daily negative reports...he's "swimming" across the floor...he's doing pratfalls...typical impulsive stuff for him).
But, even though bills arrive at my house in a day, for some reason it takes the prescriptions a week to get to me. On Wednesday night, Squirrely and I talked, and we decided that I'd just give him two 10mg capsules in the AM.
Predictably, he had a fantastic day at school, and he was really happy and proud because of that. But, of course, I was wondering--did he eat anything? Will he sleep? Will he get weepy?
He ate his lunch...he ate dinner, too. Went to bed a bit later than I would have liked.
But...HOLY MOODSWINGS, BATMAN!!! Total meltdown on the subway. He was trying to do his homework on the train...it wasn't much, and it looked to me like something he could do in that setting. He started OK, but then he started absolutely freaking out...kind of hollering, "Mommy! You aren't helping me with my homework! You hold the pen! Write it for me! Do it!!!" He was clearly having some sort of med side effect, because he was totally irrational and out of control...crying, screaming, all red, veins bulging out of his neck...
So, people are staring at us...because I'm doing what would be the wrong thing under normal circumstances if a kid were freaking out like that. I was just sitting there, as calm as I could be.
Honestly, I was almost crying, because I made the decision to give him the medication that was causing this. I knew that some sort of music, or quiet space would calm him down, but at rush hour, I had no way of doing that.
At any rate, he did calm down. And we talked about it.
He still wants to try taking the two capsules tomorrow, because I think he likes to be capable of coping in school. We agreed that during the afternoon commute, he should listen to music instead of trying to do homework. Clearly, it's just not a time of the day for him to be stressing himself out.
So...I guess everything is OK. It was just a stressful little moment in time...on the train with my child in an uncontrollable rage, and a carful of people looking at me like I'm a lax mom sitting there just not disciplining her incredibly willful child.
He took a bath when he got home. Water always calms him down. I guess that's universal. I could use a nice bath myself right now.
