Yes I did for more than a year every 2 weeks. After a year I weaned my self off the pills.
I tried the malic acid powder but it was so sour I could not stand it. I changed to organic apple cider vinegar
with the mother in it. Can't remember how much I took
I would think 1 tbs in a glass water. Could be that it was
3x a day between meals. May be you can search it.
