Congrats on your finding. It may not be the only issue going on, but if you can clearly see it then it'll help you get there.
I'm realising that I really do need to go gluten-free. Maybe I can have small amounts later on (such as a wrap) but not now.
I'm pretty interested in your feedback as it sounds fairly similar to my story.
I'm pretty healthy now for adrenal fatigue, but still some issues. The days I have medium carbs (or more), especially late at night, I don't sleep well and wake up tired. Low carb (100g or less) and I wake up feeling good. In fact, great.
I've been paying attention to gluten recently -- it's kinda forced the issue. I've known I have a milk & gluten/wheat issues since I was a teen. Milk/lactose is easy to avoid, no problems there, I think. Wheat on the other hand is everywhere. And since it's hard to avoid I'll have it once in a while. Past week I've had it twice and been grumpy/tired for two days. Noticing the exact timeframe for that is new, as until some months back I had waaay to many conflicting signals from too many things going on to figure it out.
Also, when in the post-gluten blahs, I have low discipline so eating low-carb etc. is fairly hard.
The main signal for gluten for me is pretty obvious, the bloating and lots of gas. That happens a few hours after. My left side (not right!) bloats up all the way to the chest. If it's a fair amount of gluten, then spasms start near my heart which I've concluded is my guts not being happy, but feels like the adrenaline boost from a semi-panic attack. I'm not sure which affects which but it's definitely uncomfortable.
Love to hear if others have what I mentioned in the last paragraph. I've done some research and it doesn't seem that common.
I really think I need to get gluten back off the menu again for good, THEN focus on lowish carb for the hypo. Heck at that point maybe I won't even need it :D
