His attempts to wean himself off antidepressants and antianxiety meds didn't go well so he restarted.
FYI - sometimes people will have a rebound effect when they stop antidepressants. It doesn't always mean that they have to take them - sometimes it just means they have to wean down more slowly.
I recommend no more than 10% decerease in dose PER WEEK when weaning patients off these meds. If his anxiety meds are valium or xanax related, it may take even longer.
