JoAnn, Don't the directions say to take it 30 minutes AFTER (not with as you wrote) a fatty meal? And yes, this is how I attempt to take it because there was a lot of trial and error to find out what was the method to get the best absorption of the medicine. With regards to timing, no I don't take it every 12 but I should. I error on the side of taking after I eat one of my fatty meals which is, NON OF MY SNACKS, only meals. So I take it after I eat breakfast (30 min after first bite) and after I eat dinner (30 min after first bite). I hope this helps. I think the closer you adhere to the directions the better his results will be. If you wanted you could always try a little study. After he's been on it a month following directions go and get pfts then 2 weeks later come back in doing it how it fits best into his life and see if the pft goes down at all. The other option is to change his eating routine up. Make it simple, such as a high fat greek yogurt every 12 hrs. followed by the pill 30 minutes later. In fact I might just try that! Because i do feel that I may not be getting all the benefits now that I think about it.
