I remember how horrible it was when I couldn't sleep through the night so my sympathy is with you.
I don't know what advice to give you because everyone is so different with this disease.
If you have never tried diet modification you could try removing gluten from your diet for 1 week and see if any of your symptoms get better.
It started me on my road to remission and finally a nights rest.
In remission April 2010 after 10 years of suffering and no remission ever
Jan 2010 started SCD diet (modified to remove dairy, fruit & juices)
Bleeding stopped in 3 days, 95% remission in 5.5 months
Diet: Gluten/grain-free, fructose-free (blueberries OK), dairy free (swiss cheese OK), starch-free
I eat: Protein(meat/fish/eggs,no soy), nuts(soaked/roasted), non-starch veggies, nut-flour muffins
Daily: fish oil, Vit D3 2000 2Xday with oil/fat, veggie juice, sunflower seeds, probiotic VSL#3
homemade yogurt and some fruit OK at 5.5 month remission
Highly recommend: the book "Life without Bread" and the Specific Carbohydrate Diet
