First, forget laxatives in general. For your occasional bouts of constipation take enemas. I would not go on a bowel cleanse at present. If you feel the need a bowel cleanse then go on a short juice fast, 7 days or less.
Try taking pure calcium citrate. Your diet seems to be fine but in need of more protein. Beans with Beano before hand?
Try making your own yogurt. Store bought yogurt is often somewhat dead yogurt. Get a good seed and start making your own yogurt.
No not a failure just a minor setback.
