You can have a colonoscopy without sedation. I have and it's fine. somewhat uncomfortable and certainly kind of gross, but not unbearable. also, it's nice to get the direct feedback during it.
I think you would do well to continue with this doctor for the time being. Also, when he says you can eat what you like, put another way that means you can certainly try a diet and see if it helps. I can see why without more information he's hesitant to say much more.
good luck.
I have my colonoscopy under light sedation and I'm conscious. And though it is no fun it is bearable. Getting to see your colon and immediate feed back is very nice.
For a flex scope no meds at all.
