I'm in the mid fourtys and recently determind. Eating any lettuce either on a sandwhich or just a salad. I will have some severe stomach issues. painful
stomach and diarrhea. Was waken in the middle of the night recently, feeling my stomach turning. Felt like I was going to pass out while on the toilet. I have never had any issues with any of my eating.
contamination? Have you gone to an allergist for testing to see if you are allergic to lettuce? Have you gone to a doctor to see if you have irritable bowel syndrome?
You may be dehydrated and low on electrolytes due to the diarrhea. You may want to try some G2 drink or apple juice (high in potassium) and also eating bananas.
The fact you awoke in the middle of the night with churning stomach, I wonder- are you under a lot of stress right now? Feeling highly stressed can cause a lot of problems with the digestive tract also.
