I do get constipated as part of mine, but would be hard pressed to say it's a primary symptom, except as of late. I had a lot of it before when I was on amitriptyline but since coming off of that I was back to primarily diarrhea, but over the last 3 weeks or so it's been constipation and severe nausea. In fact it got so bad this past week that I thought I was obstructed and landed in the ER (no BM for 4 days and history of stricture as well as no BM with laxatives). Turns out I was somewhat obstructed due to highly inflamed lymph nodes that were pushing on my intestine but definitely not all the way and had some pretty significant impaction as well as an infection. The plan for me right now is antibiotics and today I am going through the bowel prep used for colonoscopies to clean me out. The plan for me going forward is to be on Miralax to control the constipation when I experience it. I do like Miralax as it seems to work well and doesn't tear my stomach up like stimulants, as well as doesn't have that awful taste as in Mag Citrate, however as always check with your doc before using it. This i just my experience and doesn't mean it will or won't work for you.
