If you are already seeing evidences that he is worse, and he won't accept that, then begin a journal and keep track. Maybe once you have things written and notated date and time, it will be overwhelming evidence to him that he does need meds.

There are many ppl who, after SLOWLY weaning off their antidepressants, find they don't need them any more. But this is a process over many months or even years, and often with talk therapy to help them learn how to handle life's issues.

I just wish people would realize that it's no sin to need medication. We are human beings and thus require accurately firing systems, which includes brain chemicals. That anything, anyone, can have misfirings and need assistance is no fault of anyone, and nothing to be ashamed about. Few people have such inferior feelings with regards to having to take allergy shots/meds or such.

I hope he sees the light before something serious occurs that is difficult to reinstate. TC
