I didn't even notice that you are from Ireland until you mentioned it. Here's a link to Miralax. (Hope I'm allowed to post it.) There are generic versions of it out there as well. I've known lots of people who have tried it, including myself, and it seems to work well. http://www.miralax.com/miralax/home/index.jspa

Have you tried taking magnesium supplements?

I'm not sure of the dose for the epsom salts...I tried it years ago and found it to be a bit harsh.
