Queasy Beads prevents my son's post-op nausea

My son just had his four impacted wisdom teeth extracted last week.  I was so nervous because I have heard all kinds of horror stories about kids getting sick after waking up from anesthesia.  So, I had him wear his Queasy Beads before, during and after his surgery.  They really worked!  He said his stomach never felt queasy, not even once.  He wore them the whole day, until he went to bed, and didn't get nauseous even after taking his meds.  I was so relieved!  He never got sick!  Looks a little like a chipmunk with his swollen cheeks but he feels fine.....phew!
