I've been on miralax for a year and half now but I'm still having the same problems. I have my good days and many more bad days than good ones. I am pretty regular (except teh week before my period) and seem to go with coffee almoust every morning; however, when I go I am still bloated and feel like my BM was incomplete....I've been reading a lot about Zelnorm and how it has helped many of you with constipation problems. Does it work better tahn miralax? I would LOVE to get rid of this nasty constant bloating....I'm only 17 and I'm so tired of this. I'm going to my doctor this week to ask her about it. Also, I know it says it can only be taken for 4 to 6 weeks, but it seems like many of you have taken it longer than that? Is it okay to take it longer if it works?If my doc okays it do you think I will still take Miralax along with the zelnorm, or hopefully just the zelnorm? How long did it take for the zelnorm to work for you?any input would be appreciated!~
