Hi there,my son(19) is on venlor 150 mg,epitec 200 mg for 5 years.He recently went on a camping trip for 6 weeks and stop his meds completely.His back now, looking happen,although irritated sometimes!(psychiatrists diagnose him as bi polar in 2009).My question is must I motivate him to go back on the meds,or can he manage his depression without tabletts?Thank you Elana
