I think that the way life goes these days there is almost always a situation to attribute depression to. That said I've refused to increase meds when depressed cos you'd of had to be mad not to be depressed in those situations - and I thought that my level of depression was acceptable for the given situation.
I posted a similar thread a while back and got some great responses and decided to wait til a while after baby to change things are try and decrease meds. Similarly I think you are wise to wait till AD - after divorce to play with meds.
