After reading many posts here about people's success with Miralax as a stool softener, I decided to switch over from Dulcolax. I did notice some burning the first few days after a BM, but stuck it through and I'm very happy I did. It's been much more reliable and has really helped my healing process. I've also been applying some vaseline down there as a sort of "coating" before every BM and it seems to really help get the stool out and prevent the burning pain that comes afterwards.
Soon I will need to buy more Miralax and noticed that Costco has their own knockoff/kirkland version of Miralax called "LaxaClear". I was wondering if anyone has tried it? LaxaClear is $7 cheaper and you get 90 doses as opposed to 60 you get with Miralax. Seems like a good deal *IF* it works exactly the same. If anyone has tried it, I would love to hear how it has worked out for you.

I haven't tried it myself. Have you compared the labels and ingredients to make sure they are identical?
