I assume you have checked for allergies&#x2F;intolerances (e.g. just vegetables for two weeks and changing the physical environment around)?<p>I had effects for most of a week from my intolerances (nuts, peanuts and others), so I never really understood that I had them -- I got some allergen in me more often by pure chance.<p>The biggest effect for me was relatively mild compared to you -- sugar&#x2F;caffeine overuse to stay awake and depression. These days, my cheerful disposition would have really irritated the old me. :-)
