Yes. I've used it everyday for like 6 months now and it does nothing harmful to you. It's meant to keep things moving. And that's what it does. Docs said diarrhea can actually be a good thing in my case. It's better than constipation. And if I skip a dose or dont take enough I get bloating and bad gas pains. I take 1 cap per 8oz twice a day on a good day( so (8oz of water twice a day, each with 1 cap miralax) . And when I need to I increase my dose to 16oz water (with 2 caps) in the morning and 16 oz water (with 2 caps) in the evening. Miralax is helping me.
