Pl suggest non medication treatment.

My husband got panic attack 2 years back. Since then he took many medication. He is much better now . I believe only 10 % symptoms are there like chest pain, shoulder pain, bloating he gets and it gradually increases. He have mild ocd also since long.But he dont want to take ocd medication as medication will make him drowsy in morning and then he wont be able to focus on work/study. He tried initially medication for ocd but due to drowsiness he left. Now doctor recommended him to take clonotril 0.25 to taper it along with maxgalin75 to overcome his chest pain and shoulder pain and bloating symptoms. But now also sometime he gets cheetpaun amd bloating. He is doing meditation and exercise to overcome his symptoms. What else can be done to completely cure his anxiety problem without any medicine as its been 2 years now..
