The Psyllium in your P&B shake is known to make things like Crohn's worse. Miracle-Mineral-Supplement can also irritate if you get excessive diarrhea. I would quit taking those shakes and get the necessary fiber someplace else.
Since you don't have any serious condition you shouldn't be in any hurry to build up some large Miracle-Mineral-Supplement dose. Maybe take less drops of Miracle-Mineral-Supplement once a day instead mixed with organic grape juice. Or better yet go to Iodine supplementation instead as it will boost your immune system.
