Two things that stood out from your writing... the importance of the appendix and a burnt out ECS. So I've been having issues with 'feeling' a high. I use to feel cannabis strongly; every effect was strong... euphoria, the body calmness, etc. These days I need to smoke ALOT to get to that point, if I even get there. You're making me think that A, I have slightly burned out my receptors with poor diet choices (poor as in missing vitamins and minerals you brought up, by no means overweight etc) and B, confirming I'll need probiotics for life... had my appendix burst 2 years ago. My thoughts are a little muddled but I took notes... think about it some more and get back here after work
