I was on life support several years ago and it took awhile to recover from that. My throat would spasm while swallowing because the ventilator damaged the muscles in my throat. Plus the catheter did something too so I couldn't make it to the toilet in time. It's physically and emotionally traumatic and it all takes time to heal. I was awake too for half the time so it was especially awful. It will get better but I suspect the diuretics aren't helping the bladder situation even though it is great for your heart. Hugs
