They are changing my his medications

So the head therapist that is now over seeing my buddy's program is making a med change. She is confident she knows what one is causing the severe migraines. She is a bit concerned that it could make his depression a bit worse or put him in a dark place again so she does not want him to be alone for the next few days. Not a problem in our house lol. I'm just glad she's making the change so quickly.
