Ada,

I have experience with it but no rashes. I just didn't like it. I know people who are on opiates swear by it. But I just didn't like the way it worked. It took too long for one, I NEVER needed the full 17 grams and when I took that amount, my IBS went into a major flare. I eventually took it down to 1/2 a teaspoon and then switched over to Benefiber. More recently I talked with my PM who doesn't like Miralax either. Actually, this now makes 3 or 4 docs that don't like it. So, she wanted me to try Lactulose...love it! I don't need much of it either but no cramps, no nothing. I really think it depends on the individual and the meds though. Alot of people love it...I am just one that it didn't work all that well for and again, really didn't need all that much. Oh,my PM did say that after awhile it can start to bind you up.
