I take it regularly, about a dose and a half daily. When I asked the GI doctor if it was addictive, he laughed in a mean way (he was a mean guy) and said with my problems I was going to be dependent on something or I would never go at all. He was a real bast**d but it was the best advice I ever received. The pain I was in from fissures was much worse than childbirth, and it took about eight months, but the miralax allowed it to finally clear up.
Mine is a hereditary, progressive neuropathy. I have almost no sensation from above the knees down, and am losing muscle control slowly, so if there were improvement it would be offset by deterioration.
