Your thoughts on digestive enzymes echo my own experience recently. I recently started digestive enzymes this past month, and noticed that I had significantly more energy in the mornings beginning the first day I started taking the enzymes.
Usually, I would get completely fatigued, nauseaus and foggy minded for an hour before and an hour after going to the bathroom, pretty much every day. This process was taking a lot of energy from me and wiping me out. When I take the enzymes, I feel more normal before and after a bowel movement, and I also feel more energetic and clear minded.
