My father in law had open heart surgery, went home for recovery and had home 
health care twice a week. He had an infection then got bad enough that he had 
to return to the hospital for a few days and then went to a nursing home close 
to the doctor's office for about 2 months. He has now returned home and has 
been there about 2 weeks. His infection is starting to come back and they're 
talking about the possibility of surgery for the infection. When he returned 
home after that 2 months I gave him 1 gal. of CS and he was drinking about 4 
oz. daily. From what I am starting to hear this was probably not enough CS for 
him to take. Does anyone have some idea how much he should take daily and does 
it need to be taken once a day, twice a day, 3 times a day or what?

He is also diabetic and he is a smoker. (One of those that refuses to stop) 

Any suggestions would be greatly appreciated!

Thanks

Gary
