Steckles,
I can totally relate to what you are going through right now. I've been on zelnorm "on and off" for about a yr now. When i first started it, for about the first week or so, i couldn't leave the house...(luckily i am not working at this time) I took 6mg twice a day....finally figured out that was just too strong for me, so i just played around with the dose, depending upon my symptoms. We all know how quickly they can change!!

My symptoms seem to keep getting progressivly worse, no matter what I try, it is adversly affecting my life....there's only so much whining my DH can take, who could blame him?

I lucked out after weeks of waiting to see my gastro doc, he had a cancellation, and i was able to have a colonoscopy yesterday. The proceedure was a piece of cake, but the "prep" sucked

Having to drink those little bottles of lemon/lime fleet, and the little pills...ICK! (I am a big baby though

I Kept the first bottle down, thanks goodness and chucked the second one up

Long story short....sorry to babble,... anyway everything came back just fine, which is a relief, but yet frustrating because now I know that it is definetly IBS. He did however put me on an antispasmodic (I alternate between IBS-C & D) and also told me to try glycolax for a bit to see if it will work better for me than the zelnorm. Since my colon currently feels like a train ran over it, I will wait a day or so before trying new meds.
This truely is a frustrating disorder, and I hope you can find a balance with your zelnorm. There were times i had to go down to a 1/4 of a pill twice a day and still have the big D! But then again there are times I take the full pill 2 times daily and am sooo uncomfortably bloated and constipated
Hope you get to feeling better
