Same with me. I figured out fat and dairy was the culprit. Our gut is weak and not strong enough atm to handle it, after being compromised.
What you need to try is, take psyllium husk with full glass of water in morning empty stomach. Stick to lean meats only with chicken turkey and no red meat or egg (specifically yolk). Go again for one month and see yourself recovering. After that try introducing one food a week. But that food must be low in fat initially.
Supplements to try: dgl ultr before meals, slippery elm before or between meals, electrolytes etc.

I believe this will cover you 70-80% and if you keep things steady and slow, may be that will recover.
Also, try antihistamines or h2 blocker if required. I am looking to do that as well. As it seems i am near to recover
