Dramamine coma?

I think Alex gets car sickness.  This is a relatively new thing to me.  However, the last few long car rides have resulted in vomiting sessions in the back of the van.  

Alex seems perfectly fine and the next thing I know, he is ill.  I think it's motion sickness because he doesn't seem very sick after the episode.  It comes and goes pretty rapidly, especially if I pull the car over and stop driving somewhere. 

I pulled into Target and got Dramamine for him. It's the only medication I've heard that works for motion sickness. 

The medication definitely worked.  He was zonked out at 5:30 pm.  For a child who is loves staying awake at night, this was quite a change
