It is important to avoid sending undigested food in your intestine so as not to feed candida. I have used digestive enzymes and other enzymes. I liked the lemon and salt trick better, it acts just like HCL does, but with less risk of overacidity.
People have had success with digestive enzymes (I would not highly recommend HCL though).
Learning how to cope with the diet and digestion/ intolerance is the first step. After that you can start with the proper cleanse.
