I suffered from constipation for a long time until I found a home remedy. I made fermented cabbage drink at home which I drank 2 glasses everyday which by the way is probiotic drink. Now I also eat probiotic yogurt everyday, I was also lactose intolerant, not anymore. Lactose intolerant people should try cabbage drink first then slowly introduce yogurt to your system. For cabbage drink, one can find recipe on the you tube, it is basically chopping 1 cup of cabbage and add 6 cups of water and leave to ferment for 2 days in an air tight jar. It tastes a bit sour. I wish I had known about this earlier, I suffered for many years.
