I would eat real, whole foods and cut out sugars--nearly all sugars except stevia and honey, with cane sugar seldomly allowed. Make a food diary of what causes you problems.
I would try GOOD probiotics to see if they help any symptoms: Jarrow EPS (2-6 a day on empty stomach), Garden of Life (2-6 a day on empty stomach) or Living Streams (only available at their livingstreamsmission site) probiotic (1-2 drops, three times a day). I normally take mine in morning and night.
I would take GOOD enteric coated fish oil throughout the day. 2-4 caps of Source Naturals Ultra Potency with food--or it's equivalent in actual omegas (850mg per cap) with more EPA than DHA.
I would consider the least harmful pharmaceutical: Low Dose Naltrexone. See the top thread in treatments forum section for studies etc. This essentially halts progression and even heals some inflammation of most people. This takes time and toggling of doses if the 4.5mg doesn't do the trick.
This is the basics that I would impart to a newby. Think for yourself.
*To be sure, this is an incomplete/irresponsible/unrealistic question, and, therefore, so is my answer. It's ok, we've all been there, and you have to start somewhere. Considering 130+ people are reading this: YOUR FIRST STEP IS TO WANT TO KNOW MORE...AND MORE STILL.
