i did not intend to imply that you were not trying. Look into chaga. seriously. It's real food. Really phenomenally healing. And make sure that what you are taking in, in the way of food, not individaul supplements and cleanses, is actually what your body can use to restore its alkaline mineral stores, and counteract the acid and waste-dumping.
Obviously, you are doing plenty to try to reverse any damage. And you sound as though you knew you needed to. These things take some time. I'm not an iridologist but I think even these rings can be eliminated.
But lots of times certain kinds of cleansing can be more 'purge' than cleanse, (especially mentally) and leave you bombarded with toxins. Fear is not conducive to health.
If it calls you to some sort of wakeful or needful action, fine. Then its use has passed. This person who told you that you "will get alzhiemers" sounds like someone who feeds others fear. You don't have to believe it or accpet it. What has s/he offered you besides that "diagnosis"?
