K2, Hi. I'm so sorry I have no info on the home made yogurt. But I was told it's not supposed to do our stomachs any harm, in fact it's supposed to help the stomach. I also know that my mom used to make homemade yogurt with a machine when we were young and she really liked it. Good luck with this purchase, my feeling is that if you like yogurt you will really like this machine. I am slowly getting convinced that I should read Dr Sarno's book mindbody prescription-I'm picking it up today after work. I was sooo sick yesterday and knowing that I had a meeting this morning in desperation I started talking to my stomach-telling it I don't need it's help with all the stressful things going on in my life-like for instance my son's friend just borrowed our car (it's my car, but he uses it) and bashed it up & other stuff.... and at today's meeting which usually pushes me over the edge...I had a good experience with no incidents. I admit, I had 2 immodiums last night, but in the past having immodiums in the evening did not help me for the next day. So I'm on chicken soup and baked apple and banana today. I'm trying to help my stomach with kind foods but also asking it to mind it's own business. Maybe we have to start thinking in this way, realizing that we have a weak spot-our stomach-and when we are experiencing stressful things or even not, just plain every day stuff, our stomach jumps right in to save us, gets us all involved with pain, discomfort, the runs, we start trying different diets, thinking about bathrooms, etc.. taking our minds and emotions off from whatever it is it has to deal with. Frankly, it's of no help and is ruining my life. Don't you agree? I actually called Dr. Sarno & he returned my call. He asked me to first read his book and then, if I think I can be open to his method, will he see me. If you are interested in my progress with the book I will keep you posted. Have a great evening guys. (It's after 4 here-NY time) Sarah T.
