My doctor precribed them to me, knowing I was on Atkins, as well told me to take Potassium, But they stalled me big time, just as it says in the book.

Talk to your doctor, there is other choices, to take as suggested in Atkins, L Taurine, is one that I'm taking, My B.P. is slowly coming down, But you must check with your Dr. My b.p. was really not that high, but he was concerned, as well, it got higher after I started Atkins, which was strange.
Check out the" Nutritional and supplement thread" there is some discussions there about it, as well in the general health thread.
