Good morning. First, the colonoscopy, please dont worry! The prep is not FUN, but the test is very simple, and pain free. They give you what they call concious sedation, and you dont feel a thing!
I had the same symptoms. I would wake in the morning with LOTS of gas, then would go right to diarrhea. I had several tests, CT Scan, Ultrasound, and the dreaded

colonoscopy. I have since been diagnosed with Crohns, and been put on meds. This was just last week, so dont know yet if they work. If you are given the choice, I would take colonoscopy first as it is the best test for diagnosing. Could save you money too as you may not need the other tests. Please let us know how you are doing, and how the tests turn out. Try not to stress, (easier said than done), as that doesnt help either!
