added fiber

I was wondering if it is healthy to take metamucil about 2 thsps aday. I cannot have a normal bm without it. I was reading about the ropes thing, and it seems that I get that occasionally but only after eating dairy cheese. Any thoughts on this. My bm has never been brown, it is always yellow and pasty, and hard to eliminate unless I take metamucil. My ND is starting me on a detox, to clean my liver for the next 3 weeks, but I wonder if I need to do a bowel cleanse. I have been extremely fatigued for the last month, and they think it is stressed adrenals, my thyroid checked out normal by blood test. I wonder if my whole body is totally polluted and that is the reason for my feeling unwell. Any thoughts? Thankyou
