Your situation sounds a lot like my Mom. She had the same issues...turns out it was her GB all this time (she's 54 and suffering with it for nearly 15 years). Anyway, since she has been flushing, all symptoms disappeared and she is able now to keep up with all 7 grandkids!
She is so happy to be doing this!
I've also been doing a lot of reading about Coconut oil...super neat stuff. I had some already for a skin moisturizer, but didn't really consider it for cooking. I will be adding this into my family's diet post haste!
I will also consider flushing with it since I don't seem to have any adverse reaction so far. I just can't do the OO/GF any more.
I had some this morning and have had good energy all day...I'm excited!
