I have some of the same issues, but I found that eating that Activia Yogurt ( which is quite tastey) works well for either constipation or diarhea. It does take about a week or two to work, but it does help. I eat one in the morning and one at night. All the flavors they have out there are good to. Even the light ones are good. They also have ones with fiber. I also can tell you that sometimes eating too much fiber can stop me up. So make sure you are getting only what they call for you to eat for your size and weight. Hope whatever the issue may be, you find some relief from it. Take care!!
