Reset (nullify) Laravel/Eloquent connection

I'm using Lumen and Eloquent for the first time to build an API. I need to query the same table across several databases in one request. The algo I'm using is as follows:

foreach($db in $dbs) {
   config(['database.connections.clientdb.database' => $db]); 
   $count = MyModel->all()->count()
   $myArray[] = $count
}

Instead of getting an array of different values, the values are always the same; the value generated from the first database connection.

Since the first database is not the configured database, I know the config command works (at least once). I verified that the database name does change on each iteration. I'm not (knowingly) using a cache. I used the $mymodel = new MyModel('$db') and executing the model'ssetConnection()in the constructor then setting$mymodel = null. The value of$count` never changes.

I'm guessing the database connection isn't being released. How do I get Lumen/Laravel/Eloquent to tear down the database connection and connect to another one inside the same request?
