My Husband Has Congestive Heart Failure And Had A Quad

My husband has congestive heart failure and had a quad by-oass 8 years ago. He always took 60mg lasix but in the past two months has swollen up legs ankles, testicles etc. plus one side of his face. His cardiologist put him on 160 mg a week ago but he loses up to 6lbs overnight but puts it all back by lunchtime.
