Just type the supps you are taking. Might be imune activation if you still taking antimicrobial, could be histamine overload or some ingridients that activates your system. Also increased methylation if you still taking supps for that. Or even reactive hipoglicemia...You could use a diary for reactions after foods or supplements.
Just an example: if i eat sugars i get reactions later if i eat sulphur foods or sulphur supplement i get instant anxiety. Same happens with histamine...
