Grz you must have been in bad shape. The only time I had major problems was with the first couple of flushes, the sinus pain was so bad that the doctor, based on my symptoms, thought I should do a head scan. Of course I did not go, I also had not told him that I had done a flush.
All other different cleanses I have done never gave me any symptoms.
I am glad that you are improving.
BTW I had to give up the sole, I just did not feel well using it. I do use enough Himalayan salt.
