My husband had a stent put into his heart about 6 months ago. He now has personality change, very curt with employees he works with, argues with new employees, down right ugly on the phone with them. Still a good giving person but no longer enjoys work, says he detest working with stupid people. On meds for BP, blood thinner, and diabetes II. Feels better now that he has a CPAP but still hard on the people he works with...basically no different with me...still sweet and loving. I worry about him losing his job after 28 years...he is 55 years old. Quit smoking 2.5 years ago and no longer misses it...what can I do, will this improve?
