No BM for 2 weeks, then diarrhea!

Hello, I am new to the forum and I need some help.  I have had "constipation" issues for a few years now, but the episodes are getting worse.  I eat 35 grams of fiber a day (at least) drink 90+ oz of water and get plenty of exercise.  I clean houses daily as well.  I will not have a bowel movement for 2 weeks.  I say constipation, but for me what happens is I will wake up one day with stomach cramps and no matter what I eat or drink my stomach will cramp and I am in the bathroom with what i will describe as colon spasms!  I have soft stool all day long, for one whole day and then the cycle starts all over.  My doc gave me a Rx for miralax which did nothing. I dont feel bloated, although I might be ( been going on for so long who knows) i never feel rectal pressure or the urge to go #2 until the cramping starts one day.  I have been searching the internet but it seems everybody that complains of constipation has hard poop where mine is definately not hard!  I have an appt in a month for a colonoscopy but in the mean time has any body else experienced this situation??? From what I have read it could possibly be lazy colon ? any insight would help.....thanks

I am so sorry you are miserable! I have the exact same issue and underwent a colonoscopy and other testing, nothing was found to be causing my severe *C*. The only thing that works for me is Milk of Magnesia, and I take it the night before. It works fairly well for the most part. My *C* started and then became progressively worse in a span of around six months I would say, and it just went from there. Pretty soon, I was unable to  get by without laxatives. It is a vicious cycle! I hope you find out the cause of what is wrong!

I also get the horrid stomach rumbling/noises that goes along with it, but the only thing that quiets that is prednisone. Gas X does nothing!
