If you can afford Kefir, it has over 10 different healthy bacteria for the gut - or you could 'grow' your own. I am almost to the point where I can keep up with one more thing, so I will be growing my own soon, hopefully!!!
Otherwise, acidophilus, lots of it (!!), around 10 or more million 'units' will help. Not to mention good yogurt with live cultures, or buy acidophilus from a health food store- in the refrigerate case- is a good start.
I'm really happy that your insurance finally saw the need for your health!!! CONGRATS!!
It's been said:LD patients can be as ill as people w/ congest. heart failure & in as much pain as post-op patients.
