Yes, its in powder form. I take 1.5 the dosage everynight around 10pm. Have 1-2 BM in the morning before work.
Please beaware that it takes a few days to kick in. So you may want to wait til you are feeling a little more confident before experimenting.
Also I believe I read in a past post that Lecia has used both Miralax and MOM in combination. you may want to search the old post.
