I have slow colon mobility. nothing works for me. I tried every fiber supplement and prescription know to man. My GI put me on an old fashioned remedy. Mineral Oil and Applesauce before bed. Please talk to your GI before use. I was bed for over a year because of this issue. I went from 128lbs to 93 lbs. The reason you feel full after eating is your colon does not empyt like it should and what is in your stomach has no where to go. I get horrible spasms beneath my ribs. Actually nothing you can do but keep your colon moving. The Gi is trying to keep me away from having surgery. Good Luck...

Prayers for you!! I was diagnosed with it too.. it's horrible!! I've been constipated all my life too.. I use Trulance and Miralax and Vanilla Plant based Ensure (5mg fiber) and Thomas multigrain English muffins.. 8 mg fiber.. and no sucralose.. sucralose will kill your good gut bacteria..also take VSL3 probiotics..I went from 135 lbs to 98 ..and now overweight at 155.. but better..was in the hospital several times for it.. got colitis and ambulanced to hospital with a B/P 60 over 40.. just couldn't pass anything.. up or out..and sweated out all my fluids!! They used to bags to hydrated me on the 45 mile drive to the hospital.. sometimes I Miralax twice a day..and really watch what I eat.. lots of water and Kinderlite (not Pedilight or Gatorade ..haves sucralose).. I'll be praying for you to find exactly what works for you..I got on my knees and cried out to God.. standing on the healing scriptures!! Lifting you up to the Lord for healing!!
