Hello
So since a long time im dealing with a problem which consists of instant mood swings, brainfog and dizziness after eating. My blood sugar is ok, i tested it several times in the past.
I was sure its histamine intolerance because often foods high in histamine triggered this reaction but taking DAO producing supplements(daosin, vitamin C, b6...) antihistamines etc is often not helping at all(nearly like placebo) and those effects are often triggered by histamine-free foods. I visited doctors many times but i havent got any useless knowledge from those visits. I tried quercetin, reishi, Scutellaria baicalensis as they are natural antihistamnes and mast cell stabilizers but all of them made me only tired.
Those symptoms usually occour like 1-2 minutes after eating and are probably connected to circadian rhythm because if i eat anyting at night i pretty always feel great. i often have to drink something with caffeine to feel normal - so i thought it may be postprandial hypotension but i measured my blood pressure after eating and it was slightly higher after eating large meal which made me dizzy. Also caffeine especially guarana have delayed effect in my case- full stimulation and mood boosting effects are felt at least few hours after taking. Guarana makes mi tired and foggy and seems to work at least 6 hours after taking which often gives me insomnia,
I was thinking it may be something with serotonin in the gut as when i was taking St Johns Wort(it worked from 1-2 months and then stopped so i discontiuned using it)symptoms were minimal. Also when i was taking pregenolone in 2017 it fixed this issue while giving great procoginitve effects like mood boost, better crative thinking and verbal fluency. I thought it may have been cortisol issues but anything that lowers cortisol(Phosphatidylserine, ashvagandha..) makes me even more dizzy and gives brainfog same with cortisol rising stuff.
I have taken some probiotics in the past but they wasnt really helpful(maybe beacuse those were made by Swanson?).
I made some topic about this in the past but got no useful information from it. If you have any hypothesis why it happens and how can i fix it please write a post because this issue is a large problem for me and since visiting doctors havent helped me much i hope i can get some help here.
