Diet Questions

Hey everyone! I recently underwent a colonoscopy/endoscopy and had to do a low residue diet beforehand. I was very limited on what I could eat. No vegetables, only fruit juice, white bread, white rice, baked potatoes, butter, salt, eggs, chicken, beef and pork. In this span of 5 days I only had 1 migraine that I treated without my big medications and that was only moderate pain (for reference I am a chronic migraine sufferer and usually have 4 or more headaches a week). My question is this. I have done so many different diets and had some success on a low histamine diet but have fallen away from it some. I’ve read that a lot of people who have trouble with histamine also have trouble with oxolates. Has anyone tried or had success with this? The diet I was on was not healthy and they said I could only be on it for 5 days so doing that long term wouldn’t work. Just curious what you all have found! Thanks!
